&lt;/span&gt;
&lt;br /&gt;
Dalam pelaksanaan kegiatan usaha pertambangan, data tentang bahan galian lain dan &lt;a href=&quot;http://bongkah.blogspot.com/2008/10/mineral-acid.html&quot;&gt;mineral&lt;/a&gt; ikutan yang dijumpai harus dicatat untuk mencegah/menghindari potensi bahan galian yang terabaikan keberadaannya.
&lt;br /&gt;
Keberadaan bahan galian lain dan mineral ikutan dalam rangka kegiatan usaha pertambangan dapat terganggu saat kegiatan operasi produksi, oleh karena itu potensi yang ada perlu dikelola atau ditangani agar nilai ekonominya tidak berkurang atau hilang.&lt;br /&gt;
&lt;br /&gt;
Peluang pemanfaatan atau penanganan bahan galian lain dan &lt;a href=&quot;http://bongkah.blogspot.com/2008/10/mineral-acid.html&quot;&gt;minera&lt;/a&gt;l ikutan memerlukan kelengkapan data tentang bahan galian tersebut sejak tahapan eksplorasi, sehingga data tentang bahan galian lain dan &lt;a href=&quot;http://bongkah.blogspot.com/2008/10/mineral-acid.html&quot;&gt;mineral&lt;/a&gt; ikutan perlu disajikan secara lengkap dan sistematis sebagai dasar perencanaan kegiatan operasi produksi dan penerapan konservasi bahan galian.
&lt;br /&gt;
&lt;br /&gt;
Tipe bahan galian / &lt;a href=&quot;http://bongkah.blogspot.com/2008/10/mineral-acid.html&quot;&gt;mineral&lt;/a&gt; ikutan berdasarkan penilaian kategori teknologi kelas sumber daya dan cadangan bahan galian dan mineral ikutan dapat digolongkan menjadi 3 (tiga) tipe yaitu :
&lt;br /&gt;
1. Tipe 1 : Bahan galian lain / mineral ikutan berpotensi pengusahaan, yaitu kelompok bahan galian lain / mineral ikutan yang memiliki potensi tinggi untuk diusahakan.
&lt;br /&gt;
2. Tipe 2 : Bahan galian lain / mineral ikutan berpotensi pengembangan, yaitu kelompok bahan galian lain / mineral ikutan yang memiliki potensi sedang / menengah dan memiliki kemungkinan untuk dikembangkan sebagai komoditas usaha pertambangan.
&lt;br /&gt;
3. Tipe 3  : Bahan galian lain / mineral ikutan berpotensi sumberdaya, yaitu kelompok bahan galian lain / mineral ikutan yang memiliki potensi rendah dan belum dapat dikembangkan sebagai komoditas usaha pertambangan.</content><link rel='replies' type='application/atom+xml' href='http://bongkah.blogspot.com/feeds/59507461550654412/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment/fullpage/post/1369379201841007657/59507461550654412' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1369379201841007657/posts/default/59507461550654412'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1369379201841007657/posts/default/59507461550654412'/><link rel='alternate' type='text/html' href='http://bongkah.blogspot.com/2009/11/tipe-bahan-galian-mineral-ikutan.html' title='Tipe bahan galian'/><author><name>Artono</name><uri>http://www.blogger.com/profile/14953264256458465776</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='https://img1.blogblog.com/img/b16-rounded.gif'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1369379201841007657.post-6937565990162452512</id><published>2009-06-04T23:25:00.001-07:00</published><updated>2011-12-08T18:12:17.592-08:00</updated><category scheme="http://www.blogger.com/atom/ns#" term="a zeolite"/><category scheme="http://www.blogger.com/atom/ns#" term="fisika zeolit"/><category scheme="http://www.blogger.com/atom/ns#" term="of zeolite"/><category scheme="http://www.blogger.com/atom/ns#" term="trenggalek"/><category scheme="http://www.blogger.com/atom/ns#" term="zeolite is"/><category scheme="http://www.blogger.com/atom/ns#" term="zeolite powder"/><category scheme="http://www.blogger.com/atom/ns#" term="zeolite with"/><title type='text'>Potensi Zeolit</title><content type='html'>&lt;span style=&quot;font-size: 130%;&quot;&gt;&lt;b&gt;Potensi Zeolit

Adanya peningkatan kebutuhan akan sektor ini dan ketersediaan yang cukup banyak dan merata di Indonesia merupakan salah satu pertimbangan untuk mengeksploitasi dan mengembangkan bahan galian ini, disamping kemudahan cara penambangannya.
&lt;br /&gt;
&lt;br /&gt;
Batu kapur secara &lt;a href=&quot;http://92be.com/geology&quot;&gt;geologi&lt;/a&gt; dapat terjadi dengan beberapa cara yaitu secara organik, secara mekanik dan secara kimia. Sebagian besar batu kapur di alam terjadi secara organik, yaitu terjadi dari hasil pengendapan cangkang/rumah kerang dan siput, foraminifera atau ganggang, atau berasal dari kerangka binatang koral/kerang.
&lt;br /&gt;
&lt;br /&gt;
Batu kapur yang terjadi secara mekanik yaitu terjadi dari hasil perombakan dari hasil dari batu kapur yang sudah ada kemudian terbawa oleh arus dan kemudian diendapkan yang tidak jauh dari tempatnya semula. Sedangkan batu kapur yang terjadi secara kimia yaitu terjadi dalam kondisi iklim dan suasana lingkungan tertentu dalam air laut maupun air tawar.
&lt;br /&gt;
&lt;br /&gt;
Selain itu batu kapur dapat terjadi dari hasil peredaran air panas alam yang melarutkan lapisan batu kapur di bawah permukaan, yang kemudian diendapakan kembali di permukaan bumi.
&lt;br /&gt;
&lt;br /&gt;
Batu kapur bisa berwarna dan diklasifikasikan namanya,  tergantung dari unsur pengotornya. Magnesium, lempung, pasir, mangaan dan unsur organik merupakan unsur pengotor yang mengendap bersama-sama pada saat proses pengendapannya. Keterdapatan unsur pengotor tersebut bisa memberikan klasifikasi jenis batu kapur. Apabila unsur pengotornya magnesium, maka batu kapur tersebut diklasifikasikan sebagai batu kapur &lt;a href=&quot;http://bongkah.blogspot.com/2009/03/what-is-dolomit.html&quot;&gt;dolomit&lt;/a&gt;an, bila unsur pengotornya lempung, kama batu kapur tersebut diklasifikasikan sebagai batu kapur lempungan. Bila unsur pengotornya pasir maka disebut batu kapur pasiran.
&lt;br /&gt;
&lt;br /&gt;
Warna batu kapur yang kemerah-merahan disebabkan oleh unsur mangaan, sedangkan yang berwarna hitam bisa disebabkan oleh adanya unsur organik.
&lt;br /&gt;
&lt;br /&gt;
Batu kapur dapat bersifat keras dan padat, tetapi dapat pula sebaliknya. Selain yang pejal (masive) dijumpai yang poreus. Batu kapur juga bisa menjadi berhablur jika mengalami proses metamorfosa yaitu karena pengaruh tekanan dan panas, seperti pada batuan &lt;a href=&quot;http://marmero.com/marmer-trenggalek&quot;&gt;marmer&lt;/a&gt;. Batu kapur yang mengalami proses metamorfosa akan berubah kenampakan maupun sifat-sifatnya. Selain itu air tanah juga dapat mempengaruhi pengahbluran pada permukaan batu kapur, sehingga bisa berbentuk hablur &lt;a href=&quot;http://www.blogger.com/post-edit.g?blogID=1369379201841007657&amp;amp;postID=2062196547826217633&quot;&gt;kalsit.&lt;/a&gt;
&lt;br /&gt;
&lt;br /&gt;
Batu kapur juga bisa dijumpai di gua dan sungai bawah tanah. Ini terjadi sebagai akibat reaksi tanah. Air hujan yang mengandung CO3 dari udara maupun dari hasil pembusukan zat-zat organik di permukaan setelah meresap ke dalam tanah dapat melarutkan batu kapur yang dilaluinya, sehingga lambat laun akan terbentuk rongga-rongga di dalam tubuh batu kapur tersebut.&lt;br /&gt;
&lt;br /&gt;
Di Kabupaten Trenggalek, banyak sekali dijumpai batuan ini dan cadangannya cukup besar, tetapi belum ada investor besar yang tertarik untuk mengusahakannya. Mungkin salah satu faktornya adalah karena transportasi dan lokasinya ada di lokasi milik Perhutani.</content><link rel='replies' type='application/atom+xml' href='http://bongkah.blogspot.com/feeds/7450847202686117944/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment/fullpage/post/1369379201841007657/7450847202686117944' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1369379201841007657/posts/default/7450847202686117944'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1369379201841007657/posts/default/7450847202686117944'/><link rel='alternate' type='text/html' href='http://bongkah.blogspot.com/2009/05/batu-kapur.html' title='Batu Kapur'/><author><name>Artono</name><uri>http://www.blogger.com/profile/14953264256458465776</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='https://img1.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhYyZy9TMCi9Uh8-SnrdTi-fX3TzL9rrFNydUg-PBiXQIeHD4iafbZKdbR4rb3RpxeuY9XO8BGr1-8pnon-K9gy8atyH_D0P56-gQSUC9mPdFG6E2XZMMv4_A6515ya5HMLeDo-P8rRwNY/s72-c/Batu+Kapur+1.jpg" height="72" width="72"/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1369379201841007657.post-1641492267679963302</id><published>2009-04-12T21:39:00.002-07:00</published><updated>2013-12-12T20:17:51.314-08:00</updated><category scheme="http://www.blogger.com/atom/ns#" term="batu besi"/><category scheme="http://www.blogger.com/atom/ns#" term="besi beton"/><category scheme="http://www.blogger.com/atom/ns#" term="bijih besi trenggalek"/><category scheme="http://www.blogger.com/atom/ns#" term="harga besi"/><category scheme="http://www.blogger.com/atom/ns#" term="pasir besi"/><category scheme="http://www.blogger.com/atom/ns#" term="zat besi"/><title type='text'>Bijih Besi</title><content type='html'>&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEja-95dfApqQR8AUObKYz1AaKPQDF7cytOiZaRztm48IFCNVNH-aT1PyA9GlH-2S7ejVdAnsKw3rZ34CjQe37xoe_UMg8KHD7PnpkjyDKU75hNlJcsj3iAUySMlU6OwjeFx6TEkikpm6sk/s1600-h/Bijih+Besi.bmp&quot;&gt;&lt;img alt=&quot;&quot; border=&quot;0&quot; id=&quot;BLOGGER_PHOTO_ID_5324037752956527570&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEja-95dfApqQR8AUObKYz1AaKPQDF7cytOiZaRztm48IFCNVNH-aT1PyA9GlH-2S7ejVdAnsKw3rZ34CjQe37xoe_UMg8KHD7PnpkjyDKU75hNlJcsj3iAUySMlU6OwjeFx6TEkikpm6sk/s320/Bijih+Besi.bmp&quot; style=&quot;float: left; height: 214px; margin: 0pt 10px 10px 0pt; width: 278px;&quot; /&gt;&lt;/a&gt;&lt;span lang=&quot;IN&quot;&gt;&lt;span style=&quot;font-size: 180%;&quot;&gt;&lt;span style=&quot;color: #ff6666; font-family: arial;&quot;&gt;Bijih Besi&lt;/span&gt;&lt;/span&gt;

&lt;span lang=&quot;IN&quot;&gt;&lt;o:p&gt;&lt;/o:p&gt;Bijih besi biasanya tersusun oleh &lt;a href=&quot;http://bongkah.blogspot.com/2008/10/mineral-acid.html&quot;&gt;mineral&lt;/a&gt; magnetit (FeO Fe&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt;) yang mengandung 72,4 % Fe, ilmenit (FeO TiO&lt;sub&gt;2&lt;/sub&gt;) 36,8% Fe, hematit (Fe&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;3&lt;/sub&gt;) 69,94% Fe, goethit (FeO OH) 62% Fe, siderit (FeCO&lt;sub&gt;3&lt;/sub&gt;) 48,2% Fe. &lt;a href=&quot;http://bongkah.blogspot.com/2008/10/mineral-acid.html&quot;&gt;Mineral&lt;/a&gt; lain yang mengandung besi seperti pirit (FeS&lt;sub&gt;2&lt;/sub&gt;) 46,5% Fe, pirhotit (FeS) 63,5% Fe, tidak dapat dianggap sebagai sumber utama besi, karena kesulitan-kesulitan teknis pengolahannya. Magnetit sering diikuti oleh unsur-unsur lain seperti titanium, mangaan, magnesium dan vanadium. Endapan ini kadang-kadang mengandung emas dan platina, jika batuan pembawanya berasosiasi dengan batuan-batuan basa-ultrabasa.bahan baku untuk industri baja dan industri alat-alat rumah tangga. Hasil industri besi yang cukup terkenal disebut sebagai besi gubal (pig iron). Di beberapa negara produsen baja, belakangan ini telah terjadi peningkatan permintaan akan bijih besi. Negara-negara konsumen bijih besi  terbesar di dunia adalah seperti China, Amerika Serikat dan Jepang. &lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;

&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span lang=&quot;IN&quot;&gt;Kadar paling rendah dari endapan bijih besi yang dapat ditambang atau dikenal dengan istilah cut-off grade adalah sekitar 32% Fe, namun sekarang ini paling tidak sekitar 60% Fe baru dapat dikatakan layak untuk ditambang.&lt;/span&gt;&lt;/div&gt;

&lt;span lang=&quot;IN&quot;&gt;Di Kabupaten Trenggalek bijih besi dapat dijumpai di beberapa lokasi dan tersebar baik dalam bentuk perlapisan maupun sebagai bongkah-bongkah. Penyebaran endapan bijih besi dapat dijumpai di Desa Watuagung, Kecamatan Dongko. Jumlah total sumberdaya tereka endapan batubesi didaerah ini adalah berjumlah sekitar 88,5 juta ton.&amp;nbsp;&lt;/span&gt;&lt;/div&gt;

&lt;span lang=&quot;IN&quot;&gt;&lt;o:p&gt;&lt;/o:p&gt;Endapan bijih besi di daerah ini mempunyai karekteristik tekstur klastik dengan ukuran butir pasir, bentuk butir meruncing tanggung hingga bundar. Tersusun oleh magnetit, hematit dengan matriks mineral lempung dan semen kuarsa. Berat jenis 2,05 – 3,92 gr/cm&lt;sup&gt;3&lt;/sup&gt;. Kualitas endapan batubesi mengandung oksida besi 40,62 – 76,10% (% berat), bijih besi (ilmenit, hematit, magnetit) 46,68 – 85,94% (% berat), bijih besi (ilmenit, hematit, magnetit) 17,50 – 86 % (% volume).&amp;nbsp;&lt;/span&gt;&lt;/div&gt;

&lt;span lang=&quot;IN&quot;&gt;Sudah banyak sekali investor yang melihat lokasi bijih besi ini. &lt;/span&gt;&lt;span lang=&quot;IN&quot;&gt;Sayang, sampai saat ini belum ada investor besar yang bisa mengusahakan bijih ini. Kendala utama adalah karena lokasi ada di wilayah perhutani dan lokasi jauh dari jalan besar. &lt;/span&gt;&lt;/div&gt;

&lt;br /&gt;
&lt;br /&gt;
Dolomit merupakan variasi batugamping yang mengandung &amp;lt; 50% karbonat. Secara &lt;a href=&quot;http://92be.com/geology&quot;&gt;geologi&lt;/a&gt; dolomit dapat terbentuk karena proses primer maupun sekunder. Secara sekunder dolomit terjadi karena proses dolomitisasi yaitu proses perubahan &lt;a href=&quot;http://bongkah.blogspot.com/2008/10/mineral-acid.html&quot;&gt;mineral&lt;/a&gt; &lt;a href=&quot;http://bongkah.blogspot.com/2009/02/endapan-kalsit-merupakan-hasil.html&quot;&gt;kalsit&lt;/a&gt; menjadi dolomit, selain itu dapat juga terbentuk karena diendapkan secara tersendiri sebagai endapan evaporit. Dolomit primer berbentuk urat, yang terbentuk bersama-sama dalam jebakan bijih.
&lt;br /&gt;
&lt;br /&gt;
Dolomit mempunyai struktur kristal rhombohedral yang mempunyai komposisi kimia CaMg(CaCO3)2 atau manganodolomit dan berkomposisi MgFe(CaCO3)2 atau ferrodolomit. Umumnya dolomit berwarna putih keabu-abuan atau kebiru-biruan, kekerasan 3,5 – 4, berifat pejal, berat jenis 2,8 – 2,9, berbutir halus-kasar, mudah menyerap air, mudah dihancurkan.
&lt;br /&gt;
&lt;br /&gt;
Dolomit banyak digunakan untuk keperluan bahan bangunan, pertanian,  dalam industri dolomit banyak digunakan pada industri refraktori, tungku pemanas atau tungku pencair, meningkatkan pH tanah, sebagai pengisi dalam isndustri cat, industri kaca, plastik, kertas, bahan pembuat semen, industri alkali, pembersih air, industri ban, industri obat-obatan dan komestik, campuran makanan ternak, industri keramik, bahan penggosok.</content><link rel='replies' type='application/atom+xml' href='http://bongkah.blogspot.com/feeds/3646084361796559010/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment/fullpage/post/1369379201841007657/3646084361796559010' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1369379201841007657/posts/default/3646084361796559010'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1369379201841007657/posts/default/3646084361796559010'/><link rel='alternate' type='text/html' href='http://bongkah.blogspot.com/2009/03/what-is-dolomit.html' title='Dolomit'/><author><name>Artono</name><uri>http://www.blogger.com/profile/14953264256458465776</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='https://img1.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgzrxnLF3dycda-W2nEyQW3hbjSEPM_UNVaXbWzsARhdVJ-HSSUY63_HbsD0N3Iw7lVwDcCeETIGLUUNKMzWRtNoqOVPm_MnO2Gv8Hz__6rpv9uoN4EJpcd0238JI9wGyga35RZ8Ej8qfo/s72-c/Dolomit.jpg" height="72" width="72"/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1369379201841007657.post-890477891087749752</id><published>2009-02-16T18:34:00.000-08:00</published><updated>2011-12-08T18:13:56.216-08:00</updated><category scheme="http://www.blogger.com/atom/ns#" term="of zeolite"/><category scheme="http://www.blogger.com/atom/ns#" term="zeolite"/><category scheme="http://www.blogger.com/atom/ns#" term="zeolite a"/><category scheme="http://www.blogger.com/atom/ns#" term="zeolite for"/><category scheme="http://www.blogger.com/atom/ns#" term="zeolite powder"/><category scheme="http://www.blogger.com/atom/ns#" term="ziolite"/><title type='text'>Zeolit</title><content type='html'>&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgVXQgcujbizdfvbpyDzJsfB3IMUFQS2l70gyzjsjTzo3u84qBGlMZLLTJzJV65BxI0yYLob0EgxZUNe5Owq1Yy7CMjVJunGg5sl-OFYv4spG8lp37idDSEXczTv1JxHDogkojeOwCOYN8/s1600-h/Zeolit.jpg&quot;&gt;&lt;img alt=&quot;&quot; border=&quot;0&quot; id=&quot;BLOGGER_PHOTO_ID_5303591410300235522&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgVXQgcujbizdfvbpyDzJsfB3IMUFQS2l70gyzjsjTzo3u84qBGlMZLLTJzJV65BxI0yYLob0EgxZUNe5Owq1Yy7CMjVJunGg5sl-OFYv4spG8lp37idDSEXczTv1JxHDogkojeOwCOYN8/s320/Zeolit.jpg&quot; style=&quot;cursor: pointer; float: left; height: 201px; margin: 0pt 10px 10px 0pt; width: 269px;&quot; /&gt;&lt;/a&gt;&lt;span style=&quot;font-size: 180%;&quot;&gt;&lt;span style=&quot;color: #3366ff;&quot;&gt;Zeolit&lt;/span&gt;&lt;/span&gt;
&lt;br /&gt;
&lt;br /&gt;
Zeolit alam merupakan senyawa alumino-silikat terhidrasi dengan unsur utama yang terdiri dari kation alkali dan alkali tanah. Senyawa ini berstruktur tiga dimensi dan mempunyai pori yang dapat diisi oleh molekul air.
&lt;br /&gt;
&lt;br /&gt;
Secara &lt;a href=&quot;http://92be.com/geology&quot;&gt;geologi&lt;/a&gt; endapan zeolit terbentuk karena proses sedimentasi debu vulkanik pada lingkungan danau yang bersifat alkali (air asin), proses diagenetik (metamorfosa tingkat rendah) dan proses hidrotermal.
&lt;br /&gt;
&lt;br /&gt;
&lt;a href=&quot;http://bongkah.blogspot.com/2008/10/mineral-acid.html&quot;&gt;Mineral&lt;/a&gt; zeolit yang paling umum dijumpai adalah (Na,K)2O, Al2O3. 10 SiO2. 8H2O. Perbandingan antara atom Si dan Al yang bervariasi akan menghasilkan banyak jenis atau spesies zeolit yang terdapat di alam. Ada lebih dari 50 jenis zeolit, namun mineral pembentuk zeolit terbesar ada 9 jenis, yaitu analsim, khabazit, klinoptilolit, erionit, mordenit, ferrierit, heulandit, laumontit dan fillipsit. Di Indonesia jenis zeolit yang terbanyak adalah klinoptilolit dan mordenit

&lt;br /&gt;
&lt;br /&gt;
Endapan &lt;a href=&quot;http://allmarmer.blogspot.com/2009/02/calcite-mineral.html&quot;&gt;kalsit&lt;/a&gt; merupakan hasil retrukturisasi batugamping yang mengkristal setelah mengalami proses pelarutan. Umumnya terjadi pada batugamping atau &lt;a href=&quot;http://allmarmer.blogspot.com/2008/07/marmer.html&quot;&gt;marmer&lt;/a&gt; dalam masa kristalin yang berlapis dan berupa stalaktit dan stalakmit.
&lt;br /&gt;
&lt;br /&gt;
&lt;a href=&quot;http://allmarmer.blogspot.com/2009/02/calcite-mineral.html&quot;&gt;Kalsit&lt;/a&gt; yang berkomposisi kimia CaCO3 dapat ditemukan dalam keadaan murni dan tidak, tergantung kepada kandungan &lt;a href=&quot;http://bongkah.blogspot.com/2008/10/mineral-acid.html&quot;&gt;mineral&lt;/a&gt; pengotornya. Mineral pengotor ini terbentuk karena adanya subtitusi unsur Ca oleh unsur logam seperti Mg, Fe, Mn. Dalam prosentase tertentu &lt;a href=&quot;http://allmarmer.blogspot.com/2009/01/minerals.html&quot;&gt;mineral&lt;/a&gt; pengotor kalsit akan membentuk &lt;a href=&quot;http://bongkah.blogspot.com/2008/10/mineral-acid.html&quot;&gt;mineral&lt;/a&gt; &lt;a href=&quot;http://allmarmer.blogspot.com/2008/08/batu-kapur.html&quot;&gt;kapur&lt;/a&gt; lain seperti &lt;a href=&quot;http://bongkah.blogspot.com/2009/03/what-is-dolomit.html&quot;&gt;dolomit&lt;/a&gt;, ankerit dan kutnakorit.
&lt;br /&gt;
&lt;br /&gt;
Kalsit mempunyai benuk prismatik, tabular, rhombohedral, massive, berbutir kasar sampai sangat halus. Berat jenis kalsit murni adalah 2,71. Kalsit murni tidak berwarna dan transparan, warna akan berubah sesuai dengan subtitusi yang terjadi seperti kuning, pink, biru, lavender, kehijauan, abu-abu, hitam. Mempunyai tingkat kekerasan 3 pada skala Mohs, belahan rhombohedral.
&lt;br /&gt;
&lt;br /&gt;
Endapan kalsit sebagian besar ditemukan dalam bentuk lensa-lensa atau merupakan asosiasi endapan &lt;a href=&quot;http://allmarmer.blogspot.com/2009/01/minerals.html&quot;&gt;mineral&lt;/a&gt; yang lain, dan jarang ditemukan endapan  kalsit murni dalam ukuran besar.
&lt;br /&gt;
&lt;br /&gt;
Kalsit dipergunakan untuk keperluan pertanian, industri kimia, industri makanan, industri metalurgi, industri konstruksi.</content><link rel='replies' type='application/atom+xml' href='http://bongkah.blogspot.com/feeds/2062196547826217633/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment/fullpage/post/1369379201841007657/2062196547826217633' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/1369379201841007657/posts/default/2062196547826217633'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/1369379201841007657/posts/default/2062196547826217633'/><link rel='alternate' type='text/html' href='http://bongkah.blogspot.com/2009/02/endapan-kalsit-merupakan-hasil.html' title='Mineral Kalsit'/><author><name>Artono</name><uri>http://www.blogger.com/profile/14953264256458465776</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='16' height='16' src='https://img1.blogblog.com/img/b16-rounded.gif'/></author><media:thumbnail xmlns:media="http://search.yahoo.com/mrss/" url="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgbExEi0dpepCsIYXkuID23KcTlLzrKKYSN32dsE74S8YK6c5XAwbqaZgnlfcq7LaTQu5ijYrU1NvzteEnieUrYdtaKQVcg_fNu0vhtoeDZZv95CwAcN-JH-lfMRFgd1J1wzOEdo0w2yoE/s72-c/kalsit.jpg" height="72" width="72"/><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-1369379201841007657.post-1768749666095347623</id><published>2009-01-27T16:56:00.000-08:00</published><updated>2011-12-08T18:02:42.485-08:00</updated><category scheme="http://www.blogger.com/atom/ns#" term="bahan kaolin"/><category scheme="http://www.blogger.com/atom/ns#" term="kaolin"/><category scheme="http://www.blogger.com/atom/ns#" term="kegunaan kaolin"/><category scheme="http://www.blogger.com/atom/ns#" term="manfaat kaolin"/><category scheme="http://www.blogger.com/atom/ns#" term="mineral kaolin"/><title type='text'>Mineral Kaolin</title><content type='html'>&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg_H3kc1QitDDBZFM9z0PX04yZkrFUoQ7kE14m1tmvhqCIzlJZhAFCaVzjxdeDzhJz0PNbxIzq3XTKCikGmplStYxHrE3D-2A0G28-rlsvvqjcx4k5Wxpwr1tsZ_ApXNGK5Iqt7Hr6mq6Q/s1600-h/kaolin.jpg&quot;&gt;&lt;img alt=&quot;&quot; border=&quot;0&quot; id=&quot;BLOGGER_PHOTO_ID_5300693204021783346&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg_H3kc1QitDDBZFM9z0PX04yZkrFUoQ7kE14m1tmvhqCIzlJZhAFCaVzjxdeDzhJz0PNbxIzq3XTKCikGmplStYxHrE3D-2A0G28-rlsvvqjcx4k5Wxpwr1tsZ_ApXNGK5Iqt7Hr6mq6Q/s320/kaolin.jpg&quot; style=&quot;cursor: pointer; float: left; height: 168px; margin: 0pt 10px 10px 0pt; width: 224px;&quot; /&gt;&lt;/a&gt;&lt;span style=&quot;color: #009900; font-size: 180%;&quot;&gt;Mineral Kaolin &lt;/span&gt;
&lt;br /&gt;
&lt;br /&gt;
Kaolin merupakan masa batuan yang tersusun dari material lempung dengan kandungan &lt;a href=&quot;http://bongkah.blogspot.com/2009/04/bijih-besi.html&quot;&gt;besi&lt;/a&gt; yang rendah, dan umumnya berwarna putih atau agak keputihan. Kaolin mempunyai komposisi hidrous alumunium silikat (2H2O.Al2O3.2SiO2), dengan disertai beberapa mineral penyerta.
&lt;br /&gt;
&lt;br /&gt;
Proses pembentukan kaolin (kaolinisasi) dapat terjadi melalui proses pelapukan dan proses hidrotermal alterasi pada batuan beku felspartik, mineral-mineral potas aluminium silka dan &lt;a href=&quot;http://bongkah.blogspot.com/2009/02/mineral-feldspar.html&quot;&gt;feldspar&lt;/a&gt; diubah menjadi kaolin.  Endapan kaolin ada dua macam, yaitu: endapan residual dan sedimentasi.
&lt;br /&gt;
&lt;br /&gt;
&lt;a href=&quot;http://bongkah.blogspot.com/2008/10/mineral-acid.html&quot;&gt;Mineral&lt;/a&gt; yang termasuk dalam kelompok kaolin adalah kaolinit, nakrit, dikrit, dan halloysit (Al2(OH)4SiO5.2H2O), yang mempunyai kandungan air lebih besar dan umumnya membentuk endapan tersendiri.
&lt;br /&gt;
&lt;br /&gt;
Sifat-sifat &lt;a href=&quot;http://bongkah.blogspot.com/2008/10/mineral-acid.html&quot;&gt;mineral&lt;/a&gt; kaolin antara lain, yaitu: kekerasan 2 – 2,5, berat jenis 2,6 – 2,63, plastis, mempunyai daya hantar panas dan listrik yang rendah, serta pH bervariasi.
&lt;br /&gt;
&lt;br /&gt;
Potensi dan cadangan kaolin yang besar di Indonesia terdapat di Kalimantan Barat, Kalimantan Selatan, dan Pulau Bangka dan Belitung, serta potensi lainnya tersebar di Pulau Sumatera, Pulau Jawa, dan Sulawesi Utara.
&lt;br /&gt;
&lt;br /&gt;
Kegunaan dan manfaat kaolin banyak dipakai sebagai bahan pengisi (filler), pelapis (coater), barang-barang tahan api dan isolator. Kegunaan kaolin sangat tergantung pada karakteristiknya karena karakteristik berpengaruh terhadap kualitasnya.
&lt;br /&gt;
