- Abstract
The article presents cobalt electroextraction data using concerted electrochemical reactions, during which leaching chemical and reactions of metals transfer into solution are obtained simultaneously. Leaching was conducted in NaOH solution where leaching chemicals were obtained using sulfur-graphite electrode. Sulfur-graphite electrode served as a cathode while graphite served as anode. The optimal parameters of metals leaching into solution under experimental conditions are the following: current density 200 A/m², alkali solution initial concentration 0.2 ?, temperature 25#176;?. When leaching time increasing, cobalt extraction is also increased up to 120 minutes, after which the cobalt cooling is performed. Preliminary studies showed that concerted electrochemical reactions have prospects of using for cobalt extraction from complex and refractory raw materials.
