“…From 2009 to 2015, global cobalt production was higher than consumption, as production from new projects and from expansions to existing operations added to global supply. This trend led to a market surplus and downward pressure on prices (Shedd, 2013a, b;Searle, 2015;Spencer, 2016).…”

“…Some early predictions were made without any formalized simulation models, they represent educated guesses (Papp et al 2008;Berger et al 2011;Searle 2015;Dawkins et al 2012;Willburn 2015). Roper (2014) used a fit to an empirical model analogous to the Hubbert's model.…”

“…The ore grade is 0.6% for cobalt and considered as "high grade cobalt ore", 0.6% for copper and 0.5 g per ton rock for gold. The total resource is estimated to significantly more than 20,000 ton (Searle 2015).…”

The present business-as-usual cobalt use in society is not sustainable. Too much cobalt is lost if only market mechanisms are expected to improve recycling, and unnecessary cobalt is wasted if no policy actions are taken. Increased recycling and better conservation will be able to improve the supply situation, but this will need active policy participation beyond what market mechanisms can do alone. To conserve cobalt for coming generations, present policies must be changed within the next few decades. The sooner policies change, the better for future generations.

“…In the electrowinning of cobalt from a sulfate solution, cobalt is deposited on the cathode coupled with oxygen evolution at the anode and in chloride solutions and the deposition is coupled with chlorine gas evolution at the anode, from chloride medium [5]. Various forms of cobalt metal, including briquettes, cathode (electrolytic cobalt), fines, granules (shot), ingot, powder, and have been produced and marketed [4]. The most popular form is cathode cobalt involving sulfate…”

A hydrometallurgical process has been developed for cobalt recovery from a waste catalyst (petroleum refining Industry). This waste catalyst containing about 2.18 weight % of Co, is highly contaminated by Mg, Al, Si, Ca, Fe, Ni, Cu, Zn, Mo. The major steps are: 1) The spent catalyst is roasted with flux material in an electrical furnace at very high temperature (700˚C) for a specific duration; 2) The roasted sample is leached with sulphuric acid to bring the metal contents into solution form; 3) For separating cobalt values from the leach solution, the solution pH is raised by NaOH addition, where all cobalt content is precipitated at a pH of about 12; 4) This cobalt hydroxide precipitate is filtered and dissolved in minimum amount of sulphuric acid to get cobalt sulphate solution which is used as the electrolyte for the electrolytic recovery of cobalt. For optimizing various parameters like 1) H 2 SO 4 concentration; 2) Duration; 3) Cobalt concentration; 4) Current density; 5) Temperature; 6) Stirring etc. The particle surface morphology and deposited layers have been characterized by scanning electron microscopy (SEM). A compact metallic deposit containing 70% cobalt was obtained.
