Abstract
This invention provides a process for treating a nickel matte to recover essentially pure nickel comprising: treating an aqueous mixture of the matte with chlorine to produce a solid residue and an aqueous lixiviating solution having a pH value which is substantially nil or positive; treating the lixiviating solution to produce a solution containing primarily nickel chloride; and electrolyzing the solution to recover pure nickel at the cathode.
