Abstract

A separation method of ions of cobalt (II) and iron (III) has been proposed and studied for the case of their simultaneous presence in a solution. This method includes preliminary separation of an iron portion by alkaline precipitation with pH = 2.3, obtaining the product of simultaneous precipitation of iron and cobalt and extraction of cobalt from it by the method of cation-exchange leaching with the use of nonselective sulfonic cation resin KU-2-8.
