Chalcopyrite: Mineral Uses and Properties

Chalcopyrite: Mineral Uses and Properties

Associated ore minerals include pyrite, sphalerite, bornite, galena, and chalcocite. Chalcopyrite serves as the copper source for many secondary mineral deposits. Copper is removed from chalcopyrite by weathering or solution, transported a short distance, then redeposited as secondary sulfide, oxide, or carbonate minerals.

How Extraction of Copper from Copper Pyrites?

The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a dissimilar method from silie, carbonate or sulphate ores. The principal ore of copper is copper pyrite and copper is extracted from this ore.

Oct 15, 2016 · Pyrite is iron disulfide, FeS2 thus a sulfide. Roasting 400 degrees for about one hour should drive off the sulfur leaving just the iron to deal with maybe. Pyrite can have substantial amounts of nickel, cobalt, and gold also running with it. After roasting try the muriatic acid bath again and see what happens. Good luck with that. Ron

Pyrite: The Real Story Behind "Fool's Gold"

Apr 01, 2014 · Pyrite: The Real Story Behind "Fool's Gold". Pyrite is called "Fool's Gold" because it resembles gold to the untrained eye. While pyrite has a brassyellow color and metallic luster similar to gold, pyrite is brittle and will break rather than bend as gold does. Gold leaves a yellow streak, while pyrite's streak is brownish black.

Copper processing

Copper processing

Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent .
