| titleOfInvention | Cobalt recovery process |
| abstract | A process for producing purified cobalt from a mixture comprising metallic species of cobalt and metallic species of at least one of the group consisting of nickel and iron; said process comprising producing a metal carbonyl mixture of cobalt carbonyl and at least one of said nickel carbonyl and iron carbonyl from said metallic species mixture; separating said cobalt carbonyl from said nickel carbonyl and/or iron carbonyl; treating said cobalt carbonyl with an effective amount of a complexing gaseous admixture selected from a nitric oxide/carbon monoxide admixture and hydrogen/carbon monoxide admixture to produce a complexed cobalt carbonyl selected from cobalt nitrosyl tricarbonyl and cobalt carbonyl hydride; isolating said complexed cobalt carbonyl by distillation to provide purified complex cobalt carbonyl; decomposing said purified complex cobalt carbonyl to provide said purified cobalt and regenerated complexing gaseous mixture; and removing said regenerated complexing gaseous mixture. The process provides cobalt of improved quality in an optionally, continuous and closed-loop manner. Preferred process include either aqueous and/or gaseous process steps. |
