 · However, it is not easy to recover cobalt since there is a lack of independent cobalt deposits. Instead, cobalt is always associated with other metal minerals—for example, chalcopyrite, pyrite, carrollite, pentlandite, and so on [4]. The grade of cobalt ore is always very low and quite difficult to recover. At present, it is often extracted as a
