Copper sulphides are a group of minerals composed of copper and sulfur. They are primarily found in various geological environments, often associated with other metal ores. The most common copper sulphide mineral is chalcopyrite, which is an important source of copper for industrial use. These minerals are typically characterized by their metallic luster and dark colors, ranging from yellow to brown. Copper sulphides can be extracted through mining and are processed to obtain pure copper, which is essential for electrical wiring, plumbing, and various other applications in modern technology.
