Unless there is a very substantial lowering of production costs in Botswana or an increase in productivity or there are other external benefits provided by the government, then diamond beneficiation is unlikely to continue beyond the life of the existing mines, which are amongst the most profitable in the world. However, this is not to suggest that Hausmann and the World Bank’s conclusions

The copper-bearing solution, from the solvent extraction operations, is plated into pure copper cathodes using a process called solution exchange electrowinning (SX-EW). Stainless steel blanks are added to the plating tanks to act as cathodes and copper is plated onto them by electro-chemical deposition. It takes about a week before the cathode is ready to be removed from the tank so the

Copper production reached 69 200 t in 3Q21, 5.7% lower compared to 2Q21, mainly due to the labour disruption at Sudbury, which affected total copper production by 16 000 t in the quarter. This was partially offset by a more robust performance at Sossego, as plant availability increased in the quarter after scheduled maintenance was completed in 2Q21.

The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.150.2mm.

Copper concentrates are produced by the beneficiation, or upgrading, of copper ore. A typical copper ore would be 0.7% to 2% copper, a typical copper concentrate would grade around 25% to 35% copper. Copper concentrates are either smelted and refined in-house, or sold to custom smelters. The concentrate may be smelted to produce blister copper
