A schematic diagram of the conventional process for the production of copper and the SX/EW process can be seen here. Conventional Copper Extraction . Conventionally, copper is recovered by a pyrometallurgical process known as smelting. In this process copper ore is mined, crushed, ground, concentrated, smelted and refined.

The smelter was commissioned in 1983 as part of the Pasar project, which also involved a refinery and a precious metals plant producing doré metal. The total cost of the project was US$390M. An expansion project commenced in 1991 to increase the smelter capacity from 138kt/a copper to 172kt/a copper.

The smelter processes ore from Konkola, Nchanga and other third party concentrates and it has a capacity of 311,000t pa. The smelter has met global benchmark environmental performance as it captures 99.6% of sulphur emissions. The main refinery at Nkana uses electrolysis to process copper anodes to LME A grade copper cathodes.
The matte, which is produced in the smelter, contains 30–70% copper (depending on the process used and the operating philosophy of the smelter), primarily as copper sulfide, as well as iron sulfide. The sulfur is removed at high temperature as sulfur dioxide by blowing air through molten matte: 2 CuS + 3 O 2 → 2 CuO + 2 SO 2 CuS + O 2 ...
