Methanol and formic acid oxidation in zinc electrowinning

The anodic reaction in the electrolysis of zinc from sulphate based electrolytes is oxygen evolution, which has a standard potential of 1.23 V at 25 ºC. The lead anodes used in zinc electrowinning today have a high overpotential for oxygen evolution and the operating anode potential is as high as 2 V vs NHE.

Mechanisms of acid mist formation in electrowinning

Acid mist is generated during electrowinning in the final stage of hydrometallurgical production processes of metals including copper, zinc and nickel. In electrowinning, oxygen bubbles are formed on the anode. Burst of these bubbles at the solution/air interface produces fine acid-containing liquid droplets which become airborne and disperse throughout the workplace.

The influence of adsorbate (D2EPHA and kerosene) on the process of zinc electrowinning from sulfuric acid electrolytes was analyzed. The main objective was to critically compare three factors (1) Three types of activated carbon (AC); (2) adsorption temperatures and contact time; and (3) zinc recovery efficiency. The results showed that organic components reduced the efficiency of zinc recovery.
