Oct 11, 2017 Almost all the Co production associated with Cu comes from mining copper-cobalt ores in the DRC. 38 Due to high Co concentration in these ores (typically 0.3% Co and 3% Cu), Co is produced mainly as co-product of Cu, and producers may be driven by the value of both metals simultaneously. 39 For example, the Mutanda mine in the DRC, one of world
