The main refinery at Nkana uses electrolysis to process copper anodes to LME A grade copper cathodes. It has been expanded to accommodate the increased anode production from the Nchanga smelter. The Nchanga Tailings Leach Plant (TLP), one of the largest of its kind in the world, processes tailings from the Nchanga concentrators and stockpiled ...
Since large-scale copper production began in Zambia almost 100 years ago, the industry has experienced a lot of changes in a relatively short period of time. …
Copper processing begins with mining copper ore, which contains less than 1% of copper, and ends with sheets of 99.99% pure copper (cathodes). Copper mining generally takes place through open-pit mining, in which a series of stepped benches are dug deeper into the earth. Yet, it can also be mined underground, through horizontal tunnels.
Global mining company Anglo American has confirmed it is progressing early-stage copper exploration at a number of licences in Zambia's North-Western Province, following completion of the formation of its joint venture with a subsidiary of Arc Minerals Ltd ("Arc").

In the case of Zambia, four copper processing stages were identified in the US I-O matrix: copper ore mining (Standard Industry Classification (SIC) code 102) which also appears in the Zambian 1973 I-O table as the metal mining sector; primary copper (SIC code 3331); copper rolling and drawing (SIC code 3351); and nonferrous wire (SIC …
A two-stage leaching process is used. The first stage targets copper, and the second stage targets cobalt, allowing both copper and cobalt leach efficiencies to be optimized independently. In a one-stage leaching process, it might be possible that copper is precipitated as a sulphite salt, such as CuSO 3.Cu 2 SO 3 ·2H 2 O, which could ...
