ABSTRACT:
A method of extracting iron and nickel from sulphidic iron-nickel-materials and recover them in metallic form. The method comprises leaching the material with an acidic solution in presence of an oxidizing agent, so that substantially the whole quantity of the oxidizing agent is consumed. The obtained leaching liquid is then divided into two parts and one part is led to the cathode chamber, where iron and nickel is co-electro deposited and the other part is led to the anode chamber were the leaching liquid is regenerated before reuse.
