copper processing Definition, History, & Facts

Copper processing: Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products.

What is the role of silica in extraction of Cu from

Answer: Silica (SiO2) is used in the processes of smelting of copper pyrite (CuFeS2) ore and in conversion of produced copper matte (refined copper sulfide) into a crude metal as a flux (purifying agent). It reacts with solid impurities, such as iron oxide, and forms a liquid slag with density, smaller than the copper matte.

50.5 EXTRACTION OF METALS- METALLURGY

As already mentioned only a few most unreactive metals occur in nature in free state. Most of the metals occur in nature in oxidized form as their compounds.

12.3 Primary Copper Smelting

iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide. The copper sulfide is removed and the remaining slag is discarded. Converting produces blister copper by eliminating the remaining iron and sulfur present in the matte.
