Nickel Metal Hydride (NiMH)
Features

These cells using nickel hydroxide Ni (OH) 2 for the positive electrode (cathode). Hydrogen is used as an active element for absorbing hydrogen negative electrode (anode). This electrode consists of an alloy, usually consisting of lanthanum and metals which serves as a solid source of the reduced hydrogen and can be oxidized to obtain protons. The electrolytes are alkali, usually potassium hydroxide solutions.

Advantages

High Energy Density
Can be discharged
The use of NiMH batteries up to 3000 cycles at a discharge rate of 100% was observed. At a lower discharge, for example, at 4%, can be expected to more than 350,000 cycles
Robust - NiMH batteries tolerate overloads and extreme discharges what battery management systems simplifies
Low internal resistance
Flat discharge characteristics (falls at the end of the cycle but rapidly)
very temperature-resistant
Rapid charging in an hour is possible
Trickle charging (very slow or partial charge) can not normally be used with NiMH batteries. Chargers should therefore have timer to avoid overcharging
A repair is possible
More environmentally friendly than other cell chemistries: No cadmium, mercury or lead, and nickel can be reused
Disadvantages

Very high self-discharge rate, up to ten times higher than lead-acid or lithium batteries
Suffers from the memory effect, although this is not as pronounced as in NiCd batteries is
Battery expires due to long storage. This problem can be solved by repeatedly charging and discharging of the battery before use. This processing may also resolve the problem of the memory effect
The high discharge rate is not as good as NiCds
Less tolerant of overloads as NiCds
As with the cell must NiCds a safety valve in case of a gas formation have
Coulombischen the efficiency of nickel-hydride batteries is typically only 66%, and the decrease is directly related to the load
Even if the battery has a high capacity, this does not necessarily mean that it is also usable, since it emits only 50% of the entire energy, depending on the type of application.
The cell voltage is only 1.2V, which means that many cells are needed to produce a high-voltage battery
Lower capacity and cell voltage as alkaline primary cells.
Charge

Discharging the battery completely each month in order to avoid a memory effect
The battery can not be in the charger
Low loading rate: constant strain rate followed by maintenance charges
Rapid charging methods require dT / dt charge accounts
Timer needed to avoid long maintenance charges

Nickel metal industry at a turning point?

2012-10-03T10:27:00.003-07:00

Industrial metals have taken place since the outbreak of the financial crisis, large price fluctuations. The roller coaster ride was and is due to economic factors, as well as determined by the funding and production situation in the mining sector as well as the monetary environment in the markets. The latter has been improved by the recent expansionary measures of the major central banks.

Liquidity based courses

The third program of quantitative easing (QE3) by the U.S. Federal Reserve, the commodity prices, particularly for metals, strong drive in the coming months upwards. This proposition is the essence of a new Goldman Sachs study to the commodity market. But you have to see this prediction in the overall context. For example, the nickel price has dropped since its last high in February 2011 by about 38 percent - in the cyclical low of August this year had extended even to the minus 48 percent.

Of new records is one that is miles away. Other metals such as aluminum and copper have similar chart patterns. That prices had fallen so sharply, the weakening global economy is thanks to. Nickel is used primarily in the steel industry for the production of stainless steel. The present recession in China and the weak U.S. economy have pushed down steel consumption significantly - to say nothing of the situation across the EU. Will reduce nickel demand was with the known consequences for the world market price. On the supply side, we are dealing with a mixture of rising costs of production and high cost of capital to finance the often gigantic mining projects.
Strong pressure on prices in the mining sector

Thus, the price for a metric ton of copper production in the last ten years has doubled from 3,500 to around $ 6,000 almost, for nickel is the same relationship. Reason is the geology: Since the grade of the rock becomes less and less supported, you need more material to produce the same amount of copper, nickel and other metals. This is only possible with capital deepening and the margins of producers fall. Sooner or later the higher production costs due to price increases and then find a lower offer input into the metal trade and prices rise.

Technical analysis with positive signals

Nickel has lost since its last cyclical peak in February 2011, almost half of its value. Even more extreme, but it was after the all-time high of 2007 down, as the collapse of Lehman Brothers, the global economy in the second half of 2008 brought to falter. The price of nickel fell by 54,000 to $ 8,800. Is correspondingly high potential for recovery, the fraction of the downward trend that started in February 2011 signaled. From the perspective of technical analysis medium-term potential exists to $ 22,000, representing an increase of approximately 20 percent.

Conclusion

The market environment is currently speaking in joining the industrial metals. The central bank liquidity and the prospect of an economic turn for the better in China, the U.S. and Europe should give the metal prices in the coming months buoyancy. A certain economic risk is certainly not be explained away, and a resurgence of the Euro crisis would be negative.

Indonesian Nickel ore exports decrease due to tax

2012-07-28T11:46:00.001-07:00

Indonesian nickel ore and copper ore exports decrease due to export tax in this country.
A 20 percent export tax on various commodities resulted in commodity exports from Indonesia have declined dramatically. According to data from the Ministry of Commerce of nickel exports fell in June compared with the previous month by 80 percent to 572 000 tonnes. Exports of copper fell by 90 percent to 20,000 tons, Commerzbank reported in Commodities Daily. Bauxite, a precursor of aluminum was no longer shipped.

Indonesia is the world's third largest producer of nickel mining. With the "Grasberg Mine," where the second-largest copper mine in the world is run. When bauxite is one of the world's second largest producer. From 2014, the country is planning an export ban on metal ores. Indonesia wants more ore processed in the country itself, so that higher quality goods are exported.
Analysts see the measures for the largest customers of China not having any problems. The Middle Kingdom has established before the introduction of export tax on raw materials, various precautionary record-high inventories.

Nickel: Ceasefire in Norilsk

For the next few years by the table in any case, a merger with Rusal
and heavily indebted to the metal group Metalloinvest the world's
largest metallurgical company.
Moscow (est). About half a year, the world's largest nickel and
palladium producer, "Norilsk Nickel" buffeted by an irreconcilable
conflict between the principal owners. Now they have apparently agreed
to a constructive interaction. As Russia's Oleg Deripaska and Vladimir
Potanin top magnates (owns 29.9 per cent) on Tuesday announced that
they will lead the Group in future parity. For this purpose, four are
representatives of both sides - three independent directors and a
representative of the state - to move into the executive council.
The aim of the agreement is there, the group again on its feet.
Finally, the market capitalization of the Group by 4.5-fold to $ 13.53
billion was broken into. The devaluation had resulted in Deripaska's
Rusal had aluminum monopolist, who had purchased in April, the
blocking minority at "Norilsk Nickel", collateralize the loan taken

out for it again. At the end is the state with 4.5 billion dollars and
has been skipped so acquired under the current rules for loans also
support the right to send a representative to the group.
For the next few years by the table in any case, a merger with Rusal
and heavily indebted - as had been rumored - with the metal group
Metalloinvest the world's largest metallurgical company. "At this
stage we need to focus on solving problems that are facing our
company," said Vladimir Potanin. The verdict of the analysts on the
current ceasefire, however, fell out differently. It is pointed out
above all the confusion, what is with Deripaska's blocking minority,
with whom he has secured the state credit. Deripaska should not
refinance until the end of 2009, the share going to the state.
Was important that currently has been no nationalization and
redistribution of property and the value of the shares will now be
more predictable than during the conflict period, said Dmitry
Skvortsov, an analyst with Bank of Moscow.

A nickel mine of BHP Billiton in Australia

2010-12-02T06:25:00.000-08:00

It was not a good year so far for Hans-Joachim Welsch. Of course, even the boss says the Rogesa Roheisengesellschaft Saar Dillingen, like all German industrialists on the current recovery, but more as a private citizen. Even if Welsch hut runs under full load, the boom is in the best of Saarlanders subdued.
About the blast furnaces, from the head of one had a beautiful view over the Natural Park Saar-Hunsrück to nearby France, hangs heavy weather. Since the beginning, the prices of key raw materials iron ore and coal have more than doubled. The hut Welsch hits the mark, because these precursors along with energy costs as the - also becoming more expensive - current account for 80 percent of the cost.
The problems is not alone Rogesa. "Raw material prices and rising concern terminal, almost all sectors of the German economy," says Joachim Rotering, commodity expert at consulting firm Booz & Company.

Germany is at risk
This is for Germany a matter of survival. "Are not the raw materials to us, in the end produced where there are commodities," said Rainer Thieme, chairman of the board of the steel group Salzgitter, who is also active in the copper business. And that threatens the base in Germany, fears Ulrich Grillo, "If we do nothing, our industry has shrunk with millions of jobs and therefore our prosperity," says co-owner of the Duisburg zinc producer Grillo-Werke. In addition to work he is leading the commodity committee at the Federation of German Industries (BDI) in Berlin, this week hosted a conference on the subject.
Although there are initial signs of improvement, as is likely to increase thanks to new mines in a few years back the offer. In addition, the mining companies already play because of the growing political headwinds their power less. For an all-clear but it is still too early: "To save the high-tech location Germany have long term, the company and the German policy change fundamentally and promote remedies such as recycling and substitution," says Stahl Manager Thieme.
Peak-to-metal is nonsense
German companies have a lack partly to blame. Many had long as ThyssenKrupp own mines. "But the confidence that there would be no globalization with the increasing shortage of raw materials more, have all separately," says consultant Red Square.
They have forged the threat but four men, whose desks are up to twelve-hour flight apart. The best known is China's Premier Wen Jiabao, for its growing industry and the construction of roads or houses always need more raw materials and already imports more than half of world trade volume of iron ore and coal.

Equally important are the lesser-known leaders of the world's largest mining concerns: Roger Agnelli, Vale of Brazil, Marius Kloppers from Anglo-Australian mining giants BHP Billiton and Tom Albanese also by the British-Australian Rio Tinto. Because from the pits of the trio between the Amazon and Australia are about three quarters of the ore or coal-black-red life blood of the earth, they can determine quantities and prices almost at will.

Threat of failure in metals is less because as with oil would exceed the peak-oil-called climax of the reserves. "The talk of peak metal is nonsense, because the earth has been explored only to a small extent on possible deposits," says Peter Buchholz, Department Head Extractive Industries of the Federal Institute for Geosciences and Natural Resources in Hamburg. Dangerous for the terminal because it is often brought about artificially.

Biggest culprit is China. While German companies themselves have to take care of their raw materials, is active in China for its operations as a central purchaser. Needs, depending on the commodity up climbs to 80 percent in the year ensures competitive prices to the government with hoarding. Beijing linked in Africa or Latin America aid with delivery guarantees for metals.

At the same time, however, China secures its own minerals and semi-finished goods in the country: through open violation of the free trade such as export taxes or export bans, such as the rare earths, to which the country has almost a monopoly. "The list of violations is 450 positions," complains hut manager Welsch.

Commodity victims convened primarily to reflect the federal government speaks to the conscience, which underestimated the view of many members of the BDI-mineral deficiency. "As we speak Minister Rainer Brüderle before his trip to China earlier this month, almost manic in the conscience, and then he brings the issue of trade fouls at best, on the edge of language," laments a manager.

But the BDI congress is domestic policy. Some members of the Union the issue is burning less under the nails, because they experience the current situation is less dramatic. Thank fills the coffers of the boom, so they feel they can afford the price hikes sooner. In addition many expected in the near future with a relaxation.

This is supported by a lot: "Given the record prices it pays back, opening up new mines and those who revive the mothballed especially of smaller mining companies, as with the economic downturn two years ago, prices, expert Buchholz said of the commodity-Bundesanstalt . That should ease in two or three years, evident in almost all the minerals the deficiency, even in the rare earth metals mentioned, which are essential for high-tech products from the smartphone to laptop. There is worldwide up to 100 new mining projects that could promote to 2015 again.
Also seen in the powerful mining corporations steel Manager signs of rethinking and gentleness in price negotiations. "They see that they gradually saw off the branch on which they sit," says consultant Red Square.

The mining companies know that too high prices to their customers to encourage not only to seek new suppliers to use in future less scarce alternatives or to develop more economical methods in which to cook some steel companies also from ingredients lesser quality steel of highest quality. They provide the end even that the cabins are with the car industry and other steel customers a powerful united front and play the archdukes easily against each other. "The first signs are already there," says Stahl Manager Thieme.

In addition, the mine kings also appear in the public differently. "Almost all look back a stronger close to politicians and their home countries," says Lars Immerthal, commodities expert supply chain management consulting Brainnet. CEOs like Cynthia Carroll of Anglo-South African Anglo American want to represent their company as a responsible player. "Our contribution to developing countries is larger than development aid in many OECD countries," says the only woman to head a giant resource.

Whether BHP, Rio and Vale and - through its subsidiary De Beers - the diamond leading Anglo and with this year, probably around 170 billion dollar heavy network of the Swiss commodities trader Glencore, and its participation in Xstrata: They all seem like the new masters the world. But they need more urgent than ever, a good image and the support of the governments of its principal producing and consuming countries such as Australia, South Africa and the EU in order to approve acquisitions and new mines without stifling conditions. Every new pit is highly risky and usually pays off at the earliest in ten years, as the Serra Sul project in the Amazon, in the Vale 11.3 billion U.S. dollars for development and infrastructure, and a railway line connected.

Farewell to ex-miners

At the same time, the mine owners need help if they botch countries like China in their business. Example Rio Tinto: The Middle Kingdom was in 2009 on the state-owned Chinalco to acquire a larger share. When that did not work, Rio Tinto's senior staff were arrested in China for corruption and espionage and sentenced in an opaque process for high sentences.

So far, the image of the commodity giants in public is negative. Environmentalists complain that the mine operator with a blot on the landscape and their pits often contaminate and consume in areas without adequate drinking water a large quantity.

Governments, mining is now too powerful. Ten years ago the sector consisted mainly of small digger. But from 2001 replaced the first to BHP in the management up to that crude ex-buddy with the big shovel hands by deal-hungry ex-consultants such as the current chief Kloppers with youthful charm and a look at the edge of an ironic grin. Kloppers and his predecessor, Chip Goodyear formed in 1860 in The Hague, founded Billiton through acquisitions of iron dust Schaufler's diversified Erzkonzern. The commitment in many minerals BHP makes it less vulnerable if the economy is unstable or strike a new pit or later is completed.

The goodwill of the antitrust spoiled the corporations when they used after a decade of mergers worth almost a trillion dollars their market power to massive price increases. Most recently, almost all the major fusion projects such as BHP / Rio-Vale / Xstrata or Anglo / Xstrata failed not least due to the competition watchdogs.

However, the greater reserve of the mining concerns and new sources of raw materials for German industry are still no grounds for complacency. Ores remain scarce because of the growing global demand increases and in particular, China will continue to do almost anything to meet its needs.

Although the country is flexible when the pressure is too high. Recently was able to enforce the rest of the world a little appreciation of the Renminbi currency. But in commodities is not expected that China may be hoarding.

For behind the strategy lies neither pure evil nor the will to challenge the West, but a survival strategy. China can remain politically and economically stable only if it creates new quality jobs through growth in emerging industries.
Illegal mines

industry to secure the necessary resources in order to care little about the Chinese human rights or environmental standards in African countries - and certainly not fair world trade, "says a German industrialist. He even understanding. "The work basically like Germany to build the industry in the fifties."

Even if China complies with international standards, which often promotes the shortage, such as rare in the earth. The high-tech metals are now often made of small, illegal mines without regard for nature and safety. When cleaning up the damage China faces enormous challenges because the coveted metal is often washed with highly toxic substances such as hydrocyanic acid from the ore. In Inner Mongolia, where according to Chinese media reports, there are about 450 illegal mines, whole regions are uninhabitable. That is why Beijing wants to close many mines gradually, but that the supply shortage.

To secure the German need for raw materials in the long term, companies and policy come to fundamental changes not pass. This includes, in addition to hedging against fluctuating prices for oil, especially as an active resource management.

Consultants such Immerthal advise companies to own competence centers that know not only the trends in commodity markets. These bodies also explore which vendors could have problems, such as products live on less critical raw materials and how to secure the end essential minerals. "This reduces raw material costs by an average of five to ten percent," says Immerthal.

Second way out of the terminal is more recycling. "This is for many metals of copper to the rare earth almost without losses," says Stahl Manager Thieme.

So far, this failed in high-tech metals, the lack of supply. sort out a good 20 million mobile phones and five million computers that German consumers and businesses each year end up rarely in recycling specialists such as Umicore in Hanau, but in the domestic waste or by-nosed traders managed in other countries where the valuable contents are removed under high environmental impact - and often land in China. The export is indeed illegal, but is in practice often declared as a donation, and if he blows up, barely punished.

Therefore, the BDI here stricter controls and governmental regulations, such as a lien on equipment such as car batteries. "If things get old money," says Christian Hagelüken, chief strategist of the recycling department at Umicore, "she always manages to a collection point."

Unique in the world markets
take over the job would like Gerd Slotta, head of the specialized recycling collections Reverse Logistics Group. The Munich collect already subject to a deposit of automotive batteries, empty printer cartridges and old catalysts or are setting up a collection system using Express Post service and leading European companies.
In the long term the best way out is to research for technologies that use less critical metals and alternative materials. This not only reduces the dependence on imports, "that Germany is a unique position on the world market," says consultant Immerthal "and a strong currency in negotiations with producing countries."
For while, especially a country like Bolivia, China can only provide money for its supplies of lithium, which is in the batteries of electric cars, Germany is able to provide just and technology. To help the countries adjacent to the mining and industrial building with high-quality jobs. "This would require the German foreign policy experience a little more confident," says Immerthal.

industry Corresponding ideas does the federal government, at least Peter Ramsauer. "German politicians and industry have regarded the entire commodity supply too much as a matter of course," said Secretary of Transportation last week, when he visited Mongolia in the copper mining Oyu Tolgoi. "You can never do enough for it to secure raw material supplies." There is the hope that German businesses are not the masters of the world perhaps, but also do not have to be the servants.

nickel element

NICKEL. A silvery-white metal, symbol Ni, first isolated in 1751, but
used in alloy form with copper since ancient times. Nickel has a specific
gravity of 8.902, or a density of 0.322 lb/in3 (8,913 kg/m3), and is
magnetic up to 680°F (360°C). Its electrical conductivity is 25% that
of copper, and its thermal conductivity is 48 Btu/(ft h °F) [83 W/(m
K)]. The metal is highly resistant to atmospheric corrosion and resists
most acids, although it is attacked by oxidizing acids, such as nitric.
Sulfide ores and oxide ores are its principal sources, and its principal

use is as an alloying element in stainless steels, alloy steels, and nonferrous
metals. Nickel-cadmium and nickel-metal hydride are
battery materials. The latter, a candidate for electric-powered vehicles,
has provided twice the energy density of the common lead-acid
battery and up to 60% capacity recharge in 15 minutes. Traditionally
obtained mainly by smelting, nickel has recently been increasingly
obtained by acid-pressure leaching. Plants in Australia use sulfuric
acid to leach nickel laterite, an oxide also containing cobalt (onetenth
the nickel). The two metals are then recovered by solvent
extraction and electrowinning.

...Nickel is primarily sold for first use as refined metal (cathode, powder, briquet, etc.) or ferronickel. About 65% of the nickel consumed in the Western World is used to make austenitic stainless steel. Another 12% goes into superalloys (e.g., Inconel 600) or nonferrous alloys (e.g., cupronickel). Both families of alloys are widely used because of their corrosion resistance. The aerospace industry is a leading consumer of nickel-base superalloys. Turbine blades, discs and other critical parts of jet engines are fabricated from superalloys. Nickel-base superalloys are also used in land-based combustion turbines, such those found at electric power generation stations. The remaining 23% of consumption is divided between alloy steels,
rechargeable batteries, catalysts and other chemicals, coinage, foundry products, and plating. The principal commercial chemicals are the carbonate (NiCO3), chloride (NiCl2), divalent oxide (NiO), and sulfate (NiSO4). In aqueous solution, the divalent nickel ion has an emerald-green color....

Artificial weathering of uranium-nickel ore from Key Lake, Sask, Canada -. A contribution of uranium mineralogy to environmental protection

[Simulation of Weathering Processes of uranium-nickel ore from Key Lake, Sask, Canada -. A Contribution of Uranium Mineralogy to Environmental Protection]
von Pechmann, Edmund; Voultsidis, Vassilios

Journal of the Geological Society Volume 130 (1979), p. 513-526
Published: 01/01/1979

Abstract (German)
The effect of frost and rain stockpiled mounted uranium-nickel ore from the Key Lake deposits was studied in the laboratory. By frost damage occurs strong structure loosening and grain crushing of the rock. Sandsteinerzpartien have suffered much less than Myloniterzpartien. Uranium minerals were dissolved in the tests is minimal. The nickel minerals decompose rapidly into water-soluble secondary minerals (sulfates and arsenate). The effect of the weather conditions is dependent on the degree of comminution of the ore and its exposure to rain, frost and air.
Abstract
The impact of frost and rain on stockpiles of uranium-nickel ore from the Key Lake deposits has been investigated in simulation tests. Frost splitting causes strong disaggregation of the rock and fragmentation of the mineral grains. The ore is much less affected in the sandstone than in the mylonitized basement. During the tests, the uranium minerals have not been nearly weathered. The nickel minerals are quickly transformed into water soluble secondary minerals (sulphates and arsenate). The weathering effects on stored ore depend on the degree of comminution ore and its exposure to the atmospheric elements.
