Formula of Copper Pyrite is CuFeS2
Copper Pyrite is a copper iron sulfide mineral that crystallizes in the tetragonal system . it has the chemical formula cufes2 . it has a brassy to golden yellow color and a hardness of 3.5 to 4 on mohs scale . Its streak is diagnostic as green tinged black. Copper Pyrite is present with many ore – bearing environments via a variety of ore forming process. Copper Pyrite is an accessory Chalcopyrite is an accessory mineral in Kambalda type komatiitic nickel ore deposits, formed from animmiscible sulfide liquid in sulfide-saturated ultramafic lavas. In this environment chalcopyrite is formed by a sulfide liquid stripping copper from an immiscible silicate liquid.
i Chalcopyrite is the most important copper ore. Chalcopyrite ore occurs in a variety of ore types, from huge masses as at Timmins, Ontario, to irregular veins and disseminations associated with granitic to dioritic intrusives as in the porphyry copper deposits of Broken Hill, the American cordillera and the Andes. The largest deposit of nearly pure chalcopyrite ever discovered in Canada was at the southern end of the Temagami Greenstone Belt where Copperfields Mine extracted the high-grade copper.
