Abstract

A method for extracting noble and non-ferrous metals from refractory raw materials includes a first stage electric treatment of ground pulp in a chloride solution and a subsequent second stage of extracting commercial metals, carried out in one reactor using electrolysers with graphite anodes and steel cathodes. The reactor is fed with pulp having an S:L ratio of 1:(1-20) in a solution with a chlorine concentration of 60-180 g/L, being acidified to pH=0.2-1.0, it's agitated, the volume current density is set to 1000-10000 A/m3 and the electrolyser's voltage to 2-5 V, then maintained constant. The first stage terminates by a transition of electric current through a maximum and changing pH to 1-2. At the second stage, the cathode current density is set to 50-200 A/m2, until pH reaches 3-7. Cathode deposits of both stages are combined for further processing.
