Review of copper pyrometallurgical practice: today and ...

Abstract. The pyrometallurgical processing of copper varies worldwide with respect to the charge materials, process, operating parameters, and the physical shape, size, and orientation of the vessel. Plant operations may be either batch, semi-continuous, or fully continuous to produce blister copper or other end product.

Among the copper sulphide minerals, the main one is chalcopyrite (CuFeS. 2) comprising 50% of total copper production (CDAA, 2012). However, often present with chalcopyrite in copper orebodies are sulphide-based copper minerals which also contain arsenic.
