The issues of electrolytic precipitation of cobalt from concentrated hydrochloric acid solutions (100 g/l of metal and above) are the subject of a considerable amount of research.In the literature there is information about the possibility of obtaining electrolytic cobalt from dilute (20-30 g/l of metal) solutions. However, the data on the technological mode of the process under these conditions are extremely limited, and the quality of the resulting metal is not specified.
