Disclosed is electrolytic process for obtaining platinum having a high purity from a concentrated hydrochloric acid solution of contaminated platinum containing noble and base metal impurities, the process comprising the steps of a) providing an electrolysis cell comprising an anode compartment containing an anode and the concentrated hydrochloric acid solution of the contaminated platinum as anolyte and a cathode compartment containing a cathode and a 6 to 8 N hydrochloric acid solution as catholyte, the anode compartment being divided from the cathode compartment in the electrolysis cell by a can on exchanger membrane, b) electrolyzing the hydrochloric acid solution of the contaminated platinum in the electrolysis cell under voltage-controlled conditions by applying a voltage of from 2.5 V to 8 V across the anode and the cathode at a current density of from 0.3 to 12.5 A/dm2 to form a refined platinum-containing solution and a platinum alloy metal deposit, c) recovering the platinum alloy metal deposit, and d) obtaining the platinum of high purity from the refined platinum-containing solution.
