Selective extraction of cobalt over nickel by D2EHPA is possible for the following reasons [25–27]: • although both cobalt and nickel form hexa-aqua divalent cations, M(H 2O) 6 2+,in sulphate media, formation of the tetrahedrally coordinated cobalt species is more favourable in the organic phase than the octahedrally coordinated nickel species;

Conclusions. The present use of cobalt shows a low degree of recycling and systemic losses are significant. The reserves of cobalt are not very large (20-25 million ton extractable) as compared to metals like copper, zinc or iron, and after 2170 cobalt will have run out under a business-as-usual scenario.
