Process In Pyrometallurgy Of Copper

Pyrometallurgy | Hazen Research

In most instances, both phases are molten (such as the matte and slag in a conventional copper smelting operation). The gas phase may also be used to advantage, either as a means of separating valuable volatile constituents or for removing unwanted volatile impurities. These separation techniques form the basis of thermal smelting and refining operations.

Hydrometallurgy - Wikipedia

Hydrometallurgy is a method for obtaining metals from their ores. It is a technique within the field of extractive metallurgy involving the use of aqueous chemistry for the recovery of metals from ores, concentrates, and recycled or residual materials. Metal chemical processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy and molten salt electrometallurgy.

Pyrometallurgy - an overview | ScienceDirect Topics

As this process lacked effective environmental protection and posed a threat to human health, it was banned in China. Consequently, pyrometallurgy and pyrolysis were developed based on this thermal process (Quan et al., 2010). Pyrometallurgy is a traditional technology for recovery of non-ferrous metals as well as precious metals from waste PCBs.
