Cobalt extraction refers to the techniques used to extract cobalt from its ores and other compound ores. Several methods exist for the separation of cobalt from copper and nickel. They depend on the concentration of cobalt and the exact composition of the used ore. 1. Recovery from copper-cobalt sulfide concentrates.
Cobalt extraction - Wikipedia
1. Introduction. Cobalt is a valuable metal found in the earth's crust which is extensively used in a wide range of industrial and military applications (Tkaczyk, Bartl, Amato, Lapkovskis, & Petranikova, 2018).In recent years, due to the diverse range of its industrial application, the demand for cobalt has increased significantly and, as a result, the global production of cobalt has increased.
