Abstract
In a process for producing fine size cobalt metal powder from scrap material containing brazing compositions, the scrap is digested with hydrochloric acid to produce an aqueous cobalt acid chloride solution containing copper and silver ions which ions are removed by cementation with iron to result in a cobalt chloride solution which is processed to fine cobalt metal powder.
