Abstract
A process is divulged for recovering metals from a metal-bearing material containing, in oxidized form, more than 1% of Co, a total of Co and Ni of more than 15%, and more than 1% Mg, comprising smelting said metal-bearing material in a bath furnace together with slag formers, thereby producing an alloy phase with more than 80% of the Co, and less than 1% of the Mg, and a slag phase, by applying reducing smelting conditions, and by selecting CaO, SiO, and AlOas slag formers, in amounts to obtain a final slag composition according to the ratio's 0.25<SiO/AlO<2.5, 0.5<SiO/CaO<2.5, and MgO>10%; and separating the alloy phase from the slag phase. This process ensures quantitative recovery of Co in an alloy phase along with other metals such as Ni, while collecting Mg into a slag.
