Abstract
A process for the purification of an aqueous solution of zinc sulfate, obtained by leaching zinc ore roasted with sulfuric acid and separating the iron from the resulting solution, in which process in a first stage cu and cd are substantially completely precipitated from the solution by the addition of zinc and are separated, and in a second stage co is precipitated from the solution by the addition of zinc, an antimony compound and a soluble copper compound and separated, characterized because the second stage is carried performed at a temperature of from 65ºC to the boiling point of the solution and because at this stage the zinc is employed in an amount of at least 1 gram per liter of solution, the antimony compound is employed in an amount corresponding to 0., 4-10 mg of sb per liter of solution, and the copper compound is employed in an amount such that the proportion by weight of copper to cobalt is at least 0.2, but with a maximum corresponding to 200 mg of cu per liter of solution.
