In the present process a first metal value of a metal of which the hydroxide is insoluble is separated from a salt of the first metal and a salt of the second metal which forms a soluble ammine. The mixture is passed through an inert liquid barrier into ammonium hydroxide where the first metal is precipitated as its hydroxide and the second remains in solution as an ammine. Preferably the mixture is dripped through the liquid barrier into ammonium hydroxide below it.
