Pyrometallurgy | Pyrometallurgy, extraction and purification of metals by processes involving the application of heat. The most important operations are roasting, smelting, and refining. Roasting, or heating in air without fusion, transforms sulfide ores into oxides, the sulfur escaping as sulfur dioxide, a gas.

Flowsheet for treatment of Copper Sulfide ores rich in minerals such as chalcopyrite with gold and silver as well as arsenopyrite The above flowsheet is designed for the treatment by flotation of copper as chalcopyrite with gold and silver values.
Metal extraction from ores by heap leaching | SpringerLinkStrategies for optimizing heap leaching include ore crushing, ore agglomeration, lowcost air ventilation of sulfide ore heaps undergoing biooxidation using fans, and the use of aggregate metal extraction rate constants in making metallurgical business decisions about heap leaching.
Copper Extraction from Sulfide Ores Latest ContentsThis process is used for the extraction of copper from low grade sulfide ore. In this process, the crushed and ground ore in bulk (about 100,000 tons) is exposed to air and water in big tanks. The air in the presence of water gradually oxidizes copper and iron sulphides to their surphides.
