摘要
Abstract
Using mixed xylene as solvent ,sodium sulfite as reducing agent ,cobalt in α-nitroso-β-naphthol cobalt residue was dissolved and precipitated as cobalt sulfite .Then the precipitation was leached using hydrochloric acid to obtain cobalt chloride solution .The results show that cobalt of leaching from 15 .12 g cobalt slag ,it is need that mixed xylene of 200 mL ,sodium sulfite of 3 .27 g , water of 40 mL .Under the optimum leaching conditions of reduction reflux time of 2 h ,hydrochloric acid(1 .0 mol/L ) of 25 mL ,leaching time of 1 h ,one-stage leaching ,leaching of cobalt is 87 .48% . Cobalt chloride solution was purified by using hydrogen peroxide to remove iron ,and P204 to eliminate other impurities .The cobalt product is obtained using ammonium oxalate to precipitate from purified cobalt chloride solution and by calcination process .关键词
