Abstract. Cobalt (Co) is a potentially critical mineral. Most of its extraction is associated with a by-product of other mineral species such as copper, nickel and manganese, where it is a fundamental piece for activities that have increased their development in recent times such as electromobility, industrial and military applications.

Ore Circuit: Figure II illustrates the ore circuit. The ore, crushed to all pass 1½-inch, is fed at a regular rate to the washing and sizing screen, where 3/32-inch ore and slime are removed. From there the coarse ore goes to a slow-moving, inclined drainage conveyor, which removes surplus water and also acts as a feeder to the separator (2).
