the process used to concentrate chalcopyrite ore
Currently, the most common source of copper ore is the mineral chalcopyrite (CuFeS 2), which accounts for about 50% of copper production.The focus of this article is on the process of copper extraction from chalcopyrite ore into pure metal. Processes for other minerals are mentioned. For economic and environmental reasons, many of the …

A method of recovering copper from chalcopyrite concentrate by chemical leaching, using pyrite and silver. The catalytic properties of pyrite in the chalcopyrite leaching process are significantly enhanced by pretreating the pyrite with silver ions.
Copper extraction refers to the methods used to obtaining copper from its ores. The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
