emew Smart System. TM. Conventional electrowinning involves placing an anode and cathode into a bath of slowly circulating or stagnant electrolyte. The metal ions eventually make their way to the cathode via diffusion to be plated. With emew electrowinning, the electrolyte is circulated rapidly past the anode and cathode at a very high flow
