Cobalt is almost always a by- or co-product of mining for other metals, chiefly nickel and copper. Large quantities of cobalt also occur on the sea floor, contained within manganese nodules and cobalt-rich crusts, although further research needs to be taken to ensure the viability of this method of extraction. Sediment Hosted

Cobalt dispersed in silicates and sulphides within the host rock is remobilised and deposited in weathered layers as hydroxides and oxides near the surface and as silicate at deeper levels. These deposits are generally about 20 metres thick and mid-Tertiary to recent in age. They are principally worked for nickel with cobalt as a by-product.

 · The process begins by adding the sulfide-associated mineral to a reactor with sulfuric acid and pressurised air. This procedure removes the sulphides to obtain nickel (II) sulfate and cobalt (II) sulfate in solution. In this first dissolution stage, the sulfide is removed. NiS + 2O2 NiSO4. CoS + 2O2 CoSO4.

 · Nickel and cobalt are mostly used in alloys, e.g., stainless steels and aerospace alloys. Each has many other uses. Recycling is accomplished by prior identification and return of alloy scrap. 2010 world mine productions of nickel and cobalt were approximately 1,500,000 and 60,000 tons, respectively [ 1 ].
