| Abstract: | A new technological process for recovering cobalt from converter slag consists of cleaning of the slag in an electrical furnace, pressure leaching of granulated cobalt-rich matte, impurities removal by solvent extraction with P204, separation of cobalt from nickel by solvent extraction with P507 and production of cobalt oxide powder. This process, which has not been seen in China and abroad, has some advantages such as the employment of advanced techniques, high cobalt recovery, etc. Comparison of this process with other alternatives is described and data of a commercial scale trial for the production of cobalt oxide powder from cobalt-rich matte are given in this paper. |
