Electrowinning Nickel: The Moody Metal

Electrowinning Nickel: The Moody Metal

Unless the pH is carefully controlled, the production of acid at the anode will result in the redissolution of nickel which decreases the apparent current efficiency (CE) and needless to say the overall recovery efficiency. Conventional Nickel electrowinning cells overcome this by separating the anodic and hodic compartments of the ...
