Description

Copper scrap is smelted in primary and secondary smelters. Type of furnace and process steps depend on copper content of the secondary raw material, other constituent, size, etc. In the case of oxide scrap material, reducing conditions are required, which can be achieved through carbon and iron along with fluxing agents. Depending on the raw material and process, other metals such as Zn, Pb and Sn can be recovered from the fume. Depending on the quality/grade of the scrap, refining is required, which is usually done through electrorefining.
