Physical Properties Of Chalcopyrite

Chalcopyrite (chalcopyrite) is a kind of copper iron sulfide minerals. Chemical formula: CuFeS2, often containing trace amounts of gold, silver, etc. Tetragonal crystal system and crystal are relatively rare, as the tetrahedron shape; Many irregular granular and compact massive collection, reniform, grape aggregate. Brass yellow, sometimes porphyritic tarnish. The black streaks of microstrip green. Copper mineral chalcopyrite is a relatively common, almost can be formed in different circumstances. But they are mainly hydrothermal process and the product of the contact metasomatism, often can form a certain scale of the deposit. Origin of all over the world. In industry, it is the main raw material of copper smelting. In the field of gemology, it is seldom used alone, occasionally used as a substitute of pyrite. It is often involved in some other stones, YanShi and jade.

Class Rock Type Chalcopyrite

Class rock type chalcopyrite is a large grade low use large-scale mechanized mining ore reserves often reach hundreds of millions of tons of copper deposit copper grade is often less than 1%, according to 103 porphyry deposits in the world a single deposit ore volume average of up to 550 million tons, the grade of copper 0.6%, it is one of the important types of copper industry in the world. Known porphyry copper distribution in: (1) the Pacific rim, including the north and South America continental margin narrow porphyry copper belt, such as Canada’s los nie, Bavarian family, bingham, than, especially in the United States MoLunXi, yili, saint tower, Mexico’s o connor inside, her DE la, panama, Colorado, Peru’s mitch base tired, plug Luo Foer di praised Mr, Chile, el Roman abramovich, QiuJi mata, LaAi, dida, el Salvador and el, etc., (2) the tethys porphyry copper belt, including Hungary rex, Yugoslavia MaiDanPei grams, Iran’s sal cut shi mei black and markey Stan deposit check cover area, etc. (3) of central Asia, Mongolia, important mineral deposits have uzbek east card ear markel, kazakhstan the balkhash lake, north of WengLaDe, between the forehead, the plots of the Mongolia north-central obo was found in the south of dry Su Buer Allen Noel deposits in eastern and etc.

Sand Shale Type Of Chalcopyrite

Sand shale type copper is referring to different age stratabound copper deposits in sedimentary rocks, ore deposit is produced in a set of sedimentary rocks and sedimentary metamorphic rocks, it is one of the main industrial type copper deposits in the world, about 30% of the world copper reserves, deposit is famous for its big scale, high grade, rich associated components for characteristic, therefore its enormous economic value. This kind of deposit is widely distributed in the world, in addition to the above copper strip, and the former Soviet union more candy, jie, katz copper mine, the white pan, American western Montana extends to the southwest of bell Canada copper strip, and Bolivia’s crowe LuoTong belt and so on, in recent years, great facility in Afghanistan found copper and SaLuoBo copper all belong to the type found in Brazil.
