Process and mechanism of electrolytic enrichment of
2020-10-20 · The iron-capturing recycling technology produces Fe-PGMs alloy, of which PGMs need further enrichment for purification. We applied electrolytic refining method on Fe-PGMs alloy for separating PGMs from iron. Fe-PGMs alloy and titanium plates are used as anode and cathode. The main electrolyte is ferrous sulfate.

Electrolytic Refining - Mining Fundamentals
Electrolysis, or electrolytic refining, is a technique used for extraction, as well as purification, of metals obtained by any refining method. In the electro-refining process, a block of impure metal becomes the anode, and a thin sheet of metal becomes the cathode. Both the cathode and anode are dipped in an electrolytic cell containing an ...
