Extraction Of Copper From Its Sulphide Ores

Copper Mining and Extraction Sulfide Ores

This is not enough to make it commercially viable to extract the rock. Copper mines are only set up where there is more than 5 kg of copper per tonne of rock (0.5% by mass). Ideally, the figure should be closer to 2%. The world’s largest copper ore deposits are found in Chile on the west coast of South America. This is due to the volcanic ...

Copper Extraction from Sulfide Ores - Latest Contents

This 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. The process is completed in about one year.

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), th…
