GOLD ELECTROLYSIS REFINING PLANTS OVER 20 KG/DAY 2 X 35 LTS CELLS CAPACITY GOLD ELECTROLYSIS REFINING PLANTS OVER 30 KG/DAY 1 X 90 LTS CELL CAPACITY Electrolysis is a technological process that utilizes the electric energy generated from a current rectifier and from the technical features of acid solution. The metal to be deposited (in this case Au) is melted by a liquid solution called gold chloride. The metal to be refined is generally composed of almost pure gold (min. 995,0‰), previously melted and poured in a special mould called ANODE which will be placed to the positive pole. The cathode, a very thin plate of pure gold (999,9‰) will be placed to the negative pole. By means of a proper electromotive force and for the electrolytic bath characteristics , the metal anodes will gradually dissolve; at the same time, through the natural pole attraction between electrodes, gold migrates towards the cathode under metallic sponge form, in the plunged cathode surface.
