What is a Copper Sulfide (CuS)?

Copper Sulfide (CuS) is an inorganic compound composed of copper (Cu) and sulfur (S). It naturally occurs as part of copper ore minerals and is typically found as a black or dark gray powder. Its chemical formula is CuS, and it is commonly obtained from copper-bearing minerals such as chalcocite. Copper sulfide plays a critical role in the refining of copper and the processing of copper ores. It is used in the extraction of copper, as it is oxidized at high temperatures to produce metallic copper. Copper sulfide is also being explored for its properties in semiconductor and optical materials, and it is particularly studied for use in solar cells and light sensors.

In addition, copper sulfide is chemically stable and is sometimes used as a catalyst in certain chemical reactions. It has applications in environmental technologies and wastewater treatment, where it can be used for metal recovery and the removal of harmful substances.
