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

Chinese production of copper cathodes depends largely on imports of copper concentrates, copper scrap or other intermediate copper products, because the natural occurrence of copper in China can not satisfy the demand. In this study, the environmental impacts of the global copper supply chain of copper cathodes produced in China were assessed

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.
