Abstract of the Disclosure A solution containing a valuable metal from the group: Fe, Co, Ni, Cu, Mn, Mg, Cr, Al, Be, Cd, In, Ti and Zn, is treated with a calcium base under controlled conditions to precipitate a basic compound of the valuable metal as relatively fine particles and gypsum as relatively coarse particles. The gypsum is then separated from the compound of the valuable metal by relying on the particle size difference.
