Abstract
Acid mist abatement in base metal electrowinning cellhouses has advanced rapidly over the last 15 years as a result of both occupational health and economic pressures. Enablers include evolving designs and improved materials of construction. Cellhouse designs now typically include addition of surface tension modifying agents, cell hoods, and anode bags or anode skirts to reduce acid mist production. Automation is increasingly being considered to remove operators from the acid mist containing environment. In nickel electrowinning, chloride based anode bag technologies for chlorine recovery has been adapted to sulfate based systems. These improved technologies and design trends have resulted in cellhouse operating conditions giving greater operator comfort, while also achieving higher operational efficiency.
