The pure solutions of copper after stripping it from the loaded organic and nickel left in the raffinate were further electrolysed to produce pure copper (99.9%) and nickel (99.8%) powders, alternatively pure sulphate salts could also be crystallized. Since it is well known that Cyanex 272 is...
Copper electrodeposited from a sulphate electrolyte is freed from occluded copper sulphate and/or sulphuric acid by immediately connecting it as anode in a separate electrolytic bath consisting of water or a dilute aqueous solution. A detergent or wetting agent may be added to aid mechanically ...
The solution of Cu2+ obtained by the ion exchange may be electrolysed to recover the pure copper and generate the H+ ions which are required to replace the Cu2+ in the leaching solution. The total ion concentration of the aqueous solution is preferably maintained between 2 and 12 g/1, ...
