用硫酸和硫化钠法溶解氢氧化钴制取硫酸钴溶液的化学反应为:2Co(OH)_3+Na_2S+3H_2SO_4→2CoSO_4+Na_2SO_4+6H_2O+S为了提高钴的溶解率,减少药剂消耗,我们采用下列成分的工业氢氧化钴作试料,在不同操作制度下进行了溶解试验。Co 53.56%;Ni 0.25%;Fe 0.29%;As 0.003%;Cu 0.002%;Mn 0.82%;Zn 0.15%。
The chemical reaction of preparing cobalt sulfate solution by dissolving cobalt hydroxide with sulfuric acid and sodium sulfide is as follows: 2Co (OH) 3 + Na 2 S + 3H 2 SO 4 → 2CoSO 4 + Na 2 SO 4 + 6H 2 O + S In order to increase the dissolution rate of cobalt and reduce the consumption of medicament, The following components of industrial cobalt hydroxide as a sample, under different operating conditions of the dissolution test. Co 53.56%; Ni 0.25%; Fe 0.29%; As 0.003%; Cu 0.002%; Mn 0.82%; Zn 0.15%.
