METHOD FOR PRODUCING AQUEOUS SOLUTIONS OF COBALT SULPHATE |
| 摘要 |
Process for preparing an aqueous cobalt sulfate solution having a pH of at least 4, wherein
(a) metallic cobalt is dissolved in aqueous sulfuric acid in an atmosphere of low-oxygen air, of hydrogen or of inert gas and(b) the resulting acidic cobalt sulfate solution is treated with oxygen, oxygen-comprising gas or with a substance which can release oxygen in an aqueous medium. |

1. A process for preparing an aqueous cobalt sulfate solution having a pH of at least 4, the process comprising:
(a) dissolving metallic cobalt in aqueous sulfuric acid in an atmosphere of hydrogen, of inert gas or of a nitrogen/oxygen mixture which comprises nitrogen and oxygen in a volume ratio of from 6:1 to 100:1, thereby obtaining an acidic cobalt sulfate solution, and (b) treating the acidic cobalt sulfate solution with oxygen, oxygen-comprising gas or a substance releasing oxygen in an aqueous medium. |
