| titleOfInvention | Method of cobalt extraction from pyrite and arsenopyrite concentrates |
| abstract | The invention relates to non-ferrous metallurgy, in particular to methods for extracting cobalt from arsenopyrite and pyrite concentrates. The aim of the invention is to increase the recovery of cobalt from arsenopyrite concentrate. The method is carried out according to a pyrohydrometallurgical scheme, including sulphidizing roasting of arsenopyrite concentrate at 650-700 ° C in a neutral atmosphere to remove As, then sulphating roasting of the cinders obtained with the addition of 5% NaaSO / i at 600 ° C, followed by leaching with cobalt with a solution CAPS 1 tab. |
