University of Minnesota's Mineral Pages: Chalcopyrite

Chalcopyrite is a striking, bright yellow, metallic mineral that occurs in nearly all sulfide deposits. Initially, it may be easy to confuse chalcopyrite, or copper pyrite (CuFeS 2), with pyrite (FeS 2), but the two can be distinguished by their relative hardness and chalcopyrite's iridescent tarnish. Pyrite .

Extraction Of Copper - Chemistry

Copper Smelting means that the concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate (CaCO 3) and air in a furnace. The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulfide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag.
