Аннотация: The data of laboratory investigations of the removal of impurities (Fe, Cu, Zn, Mg, Ca) from sulfate nickel solutions are presented. It is shown that Cyanex 272[di(2,4,4-dimethylpenthyl) phosphinic acid] is the most efficient extractant. For two extraction steps by a nickel form of Cyanex 272 from a solution (after iron purification) that contained: Ni 120-130, Cu 0.8-1.0, Zn 3.0-4.0, Mg 1.5-2.0, Ca 0.4-0.8, and Fe 0.01-0.02 g/l, raffinates of the following composition are obtained: Ni 120-130, Cu, Zn, and Fe = 99.8%.
