Cobalt Ore
2.2.6 Cobalt from Central African Copper–Cobalt Ores. While most cobalt (~ 50%) is produced as a coproduct from the processing of nickel/cobalt ores, a significant amount of cobalt (~ 35%) is produced from Central African copper–cobalt ores. The remaining ~ 15% is produced from other primary sources, such as Moroccan cobalt–arsenic ores.

Nickel Statistics and Information | U.S. Geological Survey
Nickel (Ni) is a transition element that exhibits a mixture of ferrous and nonferrous metal properties. It is both siderophile (i.e., associates with iron) and chalcophile (i.e., associates with sulfur). The bulk of the nickel mined comes from two types of ore deposits: magmatic sulfide deposits where the principal ore mineral is pentlandite ...
