Abstract
In a process for producing fine size cobalt metal powder from scrap material containing brazing compositions, the silver ions are removed by cementation with iron to form an insoluble mixture which is subsequently treated with concentrated hydrochloric acid to solubilize the silver which is then precipitated as silver chloride.
