Chalcopyrite Mineral Uses and Properties Geology

Geologic Occurrence of Chalcopyrite. 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,

Copper Ore Types Sulfides vs. Oxides Investing News Network

Copper Ore Types Sulfides vs. Oxides. Both ore types can be economically mined, though they are processed in different ways. Copper sulfide ores are typically the most profitable copper ores to mine. That is because they have high copper content, and the copper in them can more easily be separated from unwanted minerals. However, copper oxide ores are more abundant.
