Aug 26, 2021· Sediment-hosted Stratiform Copper (SSC) deposits have long been an important, but often overlooked, source of copper.Accounting for about 20% of global copper (Cu) production, SSC deposits are second only to porphyries in Cu and are also the fourth-largest source of silver (Ag) and the most important source of cobalt (Co).. SSC Deposit Characteristics

The challenge: Start beneficiating oxide ore alongside sulfide ore. In the mining industry, beneficiation increases the value of the ore by removing the gangue minerals, i.e. the worthless material mixed in with the desired substance. In 2018, Comika was already beneficiating sulfide ore and moving into oxide ore.

Cobalt's supply exposure to the DRC is set to peak at 71% in 2021 and is unlikely to go below 60% before 2030F. This concentrated geopolitical supply risk is unseen in any other large-scale commodity and in is a region where supply and regulatory risks run high. Figure 14 – …
