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.
