Abstract: 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.
