What is Silica Sand?

2018-04-29T08:48:00.004-07:00

TYPES OF SAND IN NATURE AND THE DIFFERENCE BETWEEN THEM, AND THEIR ECONOMIC IMPORTANCE!

THERE ARE TWO TYPES OF SAND IN NATURE; THE FIRST IS SILICA SAND. IT IS A PURE WHITE SANDSTONE CONTAINING A HIGH PERCENTAGE OF SILICA - SIO2 MORE THAN 99%. IT CONSISTS MAINLY OF QUARTZ METAL GRANULES, CONTAINS A LOW AMOUNT OF IMPURITIES, AND HEAVY METALS LESS THAN
0.1%.

THE OTHER TYPE IS GLASS SAND. IT IS ALSO A TYPE OF SILICA SAND, WHICH IS CHARACTERIZED BY PHYSICAL AND CHEMICAL PROPERTIES THAT FIT, FOR EXAMPLE, WITH THE GLASS INDUSTRY. THE SIZE OF THE GRANULES IS OFTEN BETWEEN 100 - 500 MICRONS AND THE FE2O3 IRON OXIDE IS LESS THAN 0.05%.

Types of sand in nature and the difference between them, and their economic importance!

There are two types of sand in nature; the first is silica sand. It is a pure white sandstone containing a high percentage of silica - SiO2 »more than« 99% ». It consists mainly of quartz metal granules, contains a low amount of impurities, and heavy metals «less than 0.1%».

The other type is glass sand. It is also a type of silica sand, which is characterized by physical and chemical properties that fit, for example, with the glass industry. The size of the granules is often between 100 - 500 microns and the Fe2O3 iron oxide is less than 0.05%.

Sources of natural silica

Organic source as oil. It consists of the remains of skeletons of animals after being fossilized. The other source is the mineral source, which is the most common. This substance is found in most parts of the world because the Si element represents approximately 28% of the outer crust of the earth, about 12% of silica sand and the rest in mud form.

Silica sand is abundant in Egypt in many areas including:

* North Sinai Governorate

* Abu Zneima area in South Sinai Governorate

* Zafarana area in the Red Sea Governorate, but this region is characterized by global purity and quality of sand.

Uses of silica sand:

* Used in making glassware, crystal glass, glass panel, glass fiber, glass optics.

* Plumbing Molds.

* Reduction factor for dissolving basal oxides in solubility processes.

* Materials refined, and in the manufacture of porcelain and bricks.

* Filters in floating water stations and swimming pools.

* Extrusion material used in the manufacture of rubber, plastic, paper, paints, and in a special type of cement.

* In various chemical industries such as detergents, production of sodium silicate, paints industry, and in the manufacture of pipes.

* Used in many industrial, technical, and medical fields.

* In the field of electronics such as the manufacture of solar panels, transistors, and other devices and industrial materials that underpin the advanced technology of silicon.

The Egyptian research team, led by Dr. Ahmed El Sayed Awad, a researcher in the Operations Development Department at the Petroleum Research Institute, has created a new generation of nanocomposite polymers using silica sand in Sinai, which has increased applications in construction, Excellent properties such as "light weight, mechanical strength, corrosion resistance, low cost of fabrication, and low maintenance costs."

Classification of glass sand «Silica»:

It is classified according to the standard specifications of the producing countries. According to British specifications, glass sand is classified into 3 categories: A, B, C

For type A: Sand is fine and used in the manufacture of glass lenses, so that the ratio of silica is not less than «99.5%», and the percentage of iron oxides does not exceed «0.003%».

Class B: is a type used in the manufacture of decorative glass, and must contain silica not less than 99.5%, and the percentage of iron oxides is not more than «0.013%».

Class C is used for manufacturing glass of non-colored lenses and container glass for chemicals. Its silica content should not be less than 98.5% and the iron oxides should not exceed 0.03.

Silica sand is a natural wealth that is no less valuable than the rest of the wealth, whose material value increases after converting it from cheap raw material to the level of some other natural resources such as phosphates

Raw purification steps: -

* Chemical analysis of ore

Its purpose is to know its content mainly from silica and iron oxide, as well as check for the presence of some other secondary elements.

Phosphate Rock

2018-03-03T23:54:00.000-08:00

Phosphate Rock

Phosphate rock is a sedimentary rock contains high amounts of phosphate bearing minerals and remains of vertebrate bones.

TASFLOWRANCE produce phosphates with P2O5 30 %, 29% ,28% ,27% in jumbo bags or small bags or bulk with the chemical analysis:-

Uses phosphate Rock

Phosphates used in the detergent industry as assistant to ease water hardness , phosphates in agriculture have a three elements to feed the plants used in the fertilizer industry .

Of industrial uses of phosphate rock production of phosphoric acid and phosphate chemical production vehicles . The rock phosphate Egyptian types of phosphate relatively cannula in the world , and is exported to some of the major industrialized countries such as Japan, for many of the advanced industrial purposes . In terms of agricultural use , are the use of phosphate rock to produce calcium superphosphate fertilizer 15% ( P 2 O 5 ) Btfail rock phosphate with sulfuric acid . Used for the production of rock phosphate fertilizer calcium superphosphate ( Triple phosphate ) reaction of phosphate rock with phosphoric acid . Phosphate rock used in organic farming as well as with the use of bacteria -dissolving rock phosphate

Phosphate use in fertilizers industry

Phosphate is source of phosphor (P)

Phosphate is source of Uranium

Phosphate use in the agriculture field.

Phosphate production

Phosphate in Egypt, the most important mineral deposits from both the metallurgical and economic , because the production was, and still occupies a prominent place in the field of Mining . The reason for this is the widespread presence of phosphate in Egypt as there is in the form of a belt of phosphate deposits extends to a distance of about 750 km in length from the Red Sea coast in the east to the west Dakhla Oasis . The economic importance can be summarized in that exported abroad in large quantities and are manufactured part to the kind of chemical fertilizer super phosphate .

Phosphate sites that are of economic importance in Egypt in three main areas :

Nile Valley between Adfooukna : One of the main areas of the regions of presence Mahamed and seven- and phosphate ore reserves are estimated in the region of Mahamed alone, about 200 million tons, as the percentage of phosphorus pentoxide to about 22% . The geological studies for Ahitati is estimated at 1000 million tons of areas adjacent to the area Mahamed .

Red Sea coast between Safaga and short : phosphate exists between the ports of Safaga and short the most important areas of Mount Dawi and the thirsty and Hamrawein and estimated reserves of 200 to 250 million tons of phosphate ore .

Western Sahara: Abu weakling represent plateau between Dakhla Oasis largest deposit

of phosphate in Egypt, where an estimated crude reserves of about 1,000 million tons ,

but there are some obstacles that prevent the exploitation of exploitation. Optimized and that the presence of a significant proportion of impurities , which increases the cost of production.

Region of Upper Egypt : There configurations phosphate in the valley of the Nile in Upper Egypt on the banks of the Nile River , where there is on the east bank of the Nile in the area between Edfu and Qena and is found in all of the seven- and Mahamed Ali both East and West Banks , and returning phosphate ore in this region in a way miners exposed where there are layers of phosphate in this region very close to the Earth's surface but appear exposed on the surface immediately and then facilitates the mining and extraction of phosphate ores , and the disadvantage of phosphate ores extracted from the area of the valley in upper Egypt reduced the proportion of phosphate ore and the high proportion of impurities and then transported quantities large raw materials to manufacturing sites , raising the costs of production .

It is proposed to make a phosphate concentration in raw sites extracted and then lower

the proportion of impurities to the lowest rate and transmits phosphate semi- clean to fertilizer plants , which reduces the amount transferred and thus reduce the price of the final product of fertilizer and thus achieves economic value to the presence of phosphate ores , whether locally or in the field global Market

Eastern Desert : There phosphate ores in the Eastern Desert , distributed in three rectangles longest stretch between the Nile and the Red Sea coast, which is as follows:

Northern rectangle : only the northern line between Hurghada and Assiut , alone among the South Safaga and Qena and has ores or Huwaitat and runners-up in the south of Hurghada , Abu sharp and Dove Valley in the north of Qena .

Rectangle East and extends between Safaga and Qena up north and Qeft up short and south , and is centered around the nine sites for the phosphate ore is located mostly west of the coastal road between Safaga and short .

Rectangle South : Only the northern line runs between the short and Qeft alone south

line running between Marsa Alam and Edfu , and concentrated sites of raw materials in Westerly particular the stretch east of the Nile , where there are five sites the most famous Mahamed versus mines Seven , one of the oldest areas of phosphate mining in Egypt , where they were mining since 1897 .

Western Sahara : studies found g to identify a wide area extension includes layers of container for phosphate ores in the south of Western Sahara in both low oases emerging and low Dakhla Oasis and the plateau Abu weakling , all of which are located west of the Nile Valley and stretches west to plateau Gilf Kebir , which lies in the South Western Sahara .

And hinders the economic exploitation of phosphate ores in this region the difficulty of transporting crude to export ports for lack of means and the length of the distance. It can get rid of all these problems at the exploitation of this resource as a great strategic state

is no less important than the gold mines , which until now have not benefited from them.

Kharga , Dakhla phosphate : Other sites Kharga , Dakhla has estimated reserves Al?julo?ah tentatively . And excludes it from the site near Gibraltar northeast of

emerging low as estimated reserves Al?julo?ah tentatively estimated at 40 million tons . This site has been extracted from limited quantities of phosphate during the twenties and early thirties . And also excludes some of the sites involved in the visions that he can run the mines open and was estimated at 500 700 million tons in recognition ?julo?aa initially

Phosphate ASSISTANCE : Wrong phosphate ASSISTANCE high percentage of

impurities in it, which would lead to higher costs and lower quality, and the inability to foreign competition , which is for export outlets Foreign away from Safaga, about 500 km However Vav contains some rare metals and no fear of demand for it in the future in the global market with the growing need to fertilize crops , especially rice in Southeast Asia .

Chemical properties

Phosphate is a natural substance , consists mainly of phosphate tri calcium which is

slightly soluble in water, so it is not used directly but after treatment and improve quality by drying and purification (removal of organic material and dual carbon dioxide and separated from the clay .... ) of the most important derivatives of phosphate fertilizers, phosphate used in agriculture and phosphoric acid (H3PO4). The quality is measured by five- phosphate phosphorus oxide .

Most Ckoralvosvat exist in nature in one of the following images :

Rock phosphate of sedimentary : It is the most important sediment in terms of proliferation and size and exploitation , which constitute about 80% of the sediment

global concentration of phosphorus pentoxide which is between (20 % -30% ) , a residue free granular such as phosphate deposits in Egypt and the North Africa and the

phosphate deposits in the north of Saudi Arabia and in Iraq and Jordan.

Phosphate rocks of igneous origin : It is the result of rocks and boulders isocyanate Alnevelin Alkrbunataatat and Alberoxinat containing a significant amount of phosphate minerals of which the most important mineral apatite , and these deposits are not

common , and examples Chenba deposits in Russia .

The a result of the accumulation of waste seabirds above the limestone rock , such as deposits Enyora Island in the Pacific Ocean .

Phosphate is used in many chemical industries the most important element of the preparation of phosphorus and phosphorus acid , used in the mining industry and the military , medical, food and ceramic , fabric and Vestas . And goes most of the phosphate mined for the manufacture of fertilizer to increase crop yields in addition to the possibility of extracting some rare metals and radioactive elements . Among these elements there is a side -product of uranium which can be obtained during the conversion of phosphate into fertilizer or phosphoric acid . And containing phosphate ores desert on 200 grams of uranium per ton . (Note: Rock tons of gold contains 3 grams : 80 grams , and is fighting

it , but tons of phosphate contains 200 grams) .

The international interest in phosphates is normal, as included in the number of manufacturing industries and the most important of which uranium mining and chemical fertilizers , making it an important resource has an increasing demand by the majority of countries of the world , especially those concerned with agricultural production and defend their food security , which has become linked to a certain extent the ability of the country to get this fertilizer as a factor to increase the quantity of agricultural production , and that's what makes the demand for chemical fertilizers has very carefully in the international market , so it is not surprising that Morocco is seeking to monopoly total phosphate fertilizer , which in the current situation nearly 80% of global production of fertilizers

How is the manufacture of glass?

2014-01-14T00:56:00.000-08:00

How is the manufacture of glass?

For the manufacture of glass must be mixing a large amount of silica sand with small amounts of lime and soda and heated until it becomes a mass of high- viscosity liquid , is then formed in a certain way and then cooled to be glass .

The glass and limestone and soda ( flat glass ) glass is the most common and widely used in the world, so that the proportion of this type of glass more than (90%) of the total glass used in the world. The borosilicate glass and is the so-called glass Albaerks Alkimox and it consists of (80%) of silica and (4 % ) of alkali and (2 % ) and aluminum (13%) of boric oxide . These ratios give this type of glass three times the strength of glass soda and limestone .

The fused silica glass is composed of (100%) of silica and is considered one of the higher cost of glass and is shock resistant .

The most important characteristic of the glass is hand manufactured to his wife and that are related to temperature , so the pure silica glass has a high viscosity and requires very high temperatures to get rid of the bubbles in it .

And this thing makes it pure silica glass industry is very expensive . So for scientific reasons and necessary in order to weaken the silica glass is easily synthesized Attsada . And from experience , it is clear that the alkali metal oxides are the best way to achieve this.

And the secret lies in that each atom linked to four silicon atoms of oxygen only , and that any additional atoms of oxygen are working dislocation formation and strong and coherent component of Silicon - Oxygen - Silicon . So it became easy for us to change the silica glass installation and make it more mobile , and using alkali metal oxides .

These oxides and alkali metals smelting of the most important factors used in the glass industry , and most of these oxides are widely used soda , which is the cheapest price , have used alkaline oxides of other metals for this purpose (such as potassium and lithium ... etc) .

Budget vehicles in the glass :

There are elements and chemical compounds necessary balance in the process of manufacturing glass forms and types known according to use, including:

1 - lime : used as a solution for the manufacture of a water glass. And uses calcium and dolomitic lime in large quantities with sand and sodium carbonate and electric lamps .

2 - lead oxide : is one of the main components of the types of glass Zrani which is characterized by a high coefficient of refraction , and usually include a large proportion of potash ( glass gives luster and shine and at the same time is resistant to heat and electricity ) .

3 - oxide boric : reduces the viscosity of silica without further relaxes warming, and with the addition of a small amount of aluminum oxide maintains the transparency of the glass , and makes it more resistant to heat ( Albaerks ) , and is used in the manufacture of tools bakeries and laboratory apparatus and Alonanwib industry for their ability to withstand sudden changes in temperature and endure the effects of the chemical .

4 - aluminum oxide and lime : This mixture is used by a large margin in the glass with (10%) of boric oxide and alkali few of the fiberglass industry .

Where present silica sand in Egypt?

Silica sand or silica glass sand is the type of very pure silica sand , which is characterized by the lowest content of ferric oxide is used in the manufacture of glass types such as glass tableware, flat glass and crystal

In Egypt, the white sand located in the Red Sea Zafranah Abousnimh South Sinai , as well as other places .

But Zafranah its global excellence due to the purity and quality of the sand and the intervention of white sand in some industries such as chemical detergents in the production of sodium silicate as well as in industry and in paints and other pipes .

The company provides natural white sand with the highest quality can be found in nature , where no less than the proportion of silica oxide from 99.8 % .

13 billion tons of ore, silica sand in the kingdom awaiting investors

Amman - Petra

Said an official at the Natural Resources Authority ores Jordanian silica sand, which is estimated at about 13 billion tonnes characterized by excellent specifications being Rmala the few white impurities and Mtkhfah.

He said assistant general manager of power engineer Darwish Jasser told (Petra) that the ores silica Jordanian according to studies prepared by the Authority characterized world-class to produce glass sand, and thus the production of glass high-quality, indicating that the quantities are huge and easy mining roads surface and close to the roads and the port of Aqaba . He Gasser that studies conducted on silica sand in Jordan showed that he can get the product silica sand high purity and sand glass the size of my beloved among the (500) - 125 micron and high quality using abrasive unassembled and the separation of heavy metals using the separation helix and Altngel.

In this regard, he said, "because of the relatively few impurities in the raw material has been possible to produce high purities and large retrieval by using this method."

According to Gasser, the investment opportunities in this crude, which is concentrated in the southern regions available to investors and companies specialized in processing these ores competition values added to the intervention in the different uses for reasons of export regionally and globally, referring to the potential good that provided raw to invest in the production of glass, especially in the absence of a glass factory in the Kingdom.

And uses raw said Gasser he uses in the manufacture of glass and crystal glass, fiberglass and glass optics and molds plumbing, pointing out that the glass sand high-quality product from my head the Negev and the Siq possible compared with the degree of (a) in the specifications of British glass sand used for the production of glass optics. Also uses raw silica sand Jordanian agent reduced the degree of melting of the oxides basal and processes of melting and as a refinement in the manufacture of ceramics, bricks, noting that crude is also used in filters purify water and enters in the manufacture of plastics, rubber, paint, paper and chemical industries different.

And places a raw said Gasser that glass sand found in areas of the head of the Negev and the bottom of the Disi and Petra and Ain Beida, pointing out that the thickness of sand Disi up to 300 meters while bringing fish raw in Wadi Siq and the Aljeicah Aqaba to 200 meters.

And investment situation, Gasser said number of المرامل to operate in the Kingdom in the top of the Negev region for the use of construction materials and two local companies are working on the production of small amounts of washed sand and ground, stressing that there are investment opportunities for investors and companies to work multiple industries and real. And silica sand (sand quartz) is a rock sand pure white with a high percentage of silica, which consists mainly of granulated quartz mineral and contain a small amount of impurities and heavy metals, while The term glass sand on silica sand (quartz) that have physical and chemical specifications commensurate with the glass industry.

Tossicologia

L'inalazione può predisporre a malattie polmonari dei minatori.

Caolino è un silicato di alluminio idrato. È naturalmente come argilla che è preparato per uso farmaceutico mediante lavaggio con acqua per rimuovere sabbia e altre impurità.

Storia

Caolino è stato usato commercialmente e in medicina per centinaia di anni. Attualmente è utilizzato per la fabbricazione di ceramiche, mattoni, cemento, ceramica, vernici, materiale intonaci, lacche coloranti (coloranti insolubili) e isolanti. Come materia prima, si trova comunemente in carta, plastica, cosmetici e farmaceutici, 2 ed è utilizzato anche in preparazioni farmaceutiche, come agente filtrante per chiarire liquidi. Evidenza suggerisce anche che caolino può essere utile nel decolorazione delle acque reflue colorante mediante il metodo elettrocoagulazione. 3 Quando applicato localmente, serve come agente emolliente e asciugatura. Quando ingerito, agisce come adsorbente per legare tossine gastrointestinali e diarrea controllo.

Caolino è stato aggiunto a spolverando polveri e viene utilizzato come eccipiente compressa. Viene anche utilizzato in una varietà di test automatizzati chimica di laboratorio, compresa la determinazione del tempo di coagulazione attivato (ACT) 4 e nel sierodiagnosi della tubercolosi utilizzando il test di agglutinazione caolino (KAT). 5 Caolino è stato utilizzato anche per indurre sperimentalmente idrocefalo in modelli animali per valutare gli effetti della condizione sullo sviluppo sensomotorio. 6

Chimica

Caolino ha la formula approssimata chimica di H 2 Al 2 Si 2 O 8 (H 2 O) ed è una polvere bianca o giallo-bianco che ha un aspetto leggermente oleosi. 7 è un alluminosilicato rispettose dell'ambiente minerale che è insolubile in acqua. 1 caolino luce è il materiale preferito per l'impiego in preparazioni farmaceutiche. Le particelle finemente divise produrre una superficie molto grande che assorbe una grande varietà di composti.

Caolino capacità di aumentare la produzione di acido citrico da Aspergillus niger, un fungo termofila, è stato studiato. Sospensioni acquose di caolino sono stati aggiunti al terreno fungo in concentrazioni di 5 a 25 ppm.
