The copper-cobalt deposits hosted in the sedimentary sandstone and the cobalt-bearing magmatic Cu-Ni sulphide deposits are two kinds of the most important cobalt deposits.

This paper is based on cobalt mineral resources in the world today, classification of cobalt deposits and the latest advances of exploration and research on cobalt deposits home and abroad.

Researches show that the south of the Katangan copper-cobalt belt between Kolwezi and Likasi in Central Africa is a region of prospecting potential for the elluvium-deluvial cobalt deposits.
