Nickel Electrowinning - Metallurgist & Mineral Processing Engineer
Electrowinning experiments were conducted to recover nickel from the dilute leach electrolyte that had been purified of copper and iron to the levels of 0.003 and 0.02 g/l, respectively. After a few preliminary electrolyses an electrodeposit containing 84 pct Ni was attained from a solution containing 0.75 g/l nickel ion (table 2).
