Treatment Of Sulphate Leach Liquors To Recover Cobalt From Waste Dusts Generated By The Glass Industry

A hydrometallurgical process has been developed for cobalt recovery from a waste dust formed during the colouring of glass plates. This dust, containing about 33% Co, is highly contaminated by Fe and Cr. The process consists of the following steps: Leaching the dust in H2SO4; Purification of leach liquors by hydrolytic precipitation using Na2CO3 and/or K2CO3 as neutralising agent; Precipitation of basic cobalt(II) carbonate; Dissolution of basic cobalt(II) carbonate in sulphuric acid and separation of residual chromium; Electrowinning of cobalt from refined sulphate solutions. A compact metallic deposit containing >99.5% Co was obtained.
