Zambia's history of copper production — Part 2

I n Part 1 of Zambia's history of copper production, we reflected on the country's progression from the early days of large-scale production of the red metal almost 100 years ago, to the challenges that led to the re-privatisation of the industry at the end of the last century.In Part 2, we take a look at how Zambia's copper mining journey continued in the years that followed, when

CESL Process - Teck

Pressure Oxidation: All copper minerals are oxidized into an acid-soluble solid (basic copper sulphate). Example: Oxidation of chalcopyrite (6CuFeS 2 + 7.5O 2 + 2H 2 SO 4 + 2H 2 O -> 2[CuSO 4 2Cu(OH)2] + Fe 2 O 3 + 12S°) The sulphur and the hematite (Fe2O3) solids do not leach or react in the subsequent stages of the CESL Process and are disposed of in their current forms as tails.
