3M™ Acid Mist Suppressant is a fluorochemical additive that provides outstanding sulfuric acid mist suppression in the copper electrowinning tankhouse without the formation of a stable foam blanket at the surface of the electrowinning cell. Acid mist levels can be reduced significantly when 3M™ Acid Mist Suppressant is used alone or in conjunction with mechanical barriers, such as polypropylene macrospheres, with no adverse effects to either the solvent extraction or electrowinning process.

Features

• Quick-draining, short term foam blanket
• May be used alone or in conjunction with mechanical barriers
• Can be added directly to the tankhouse electrolyte
• Compatible with solvent extraction organics

Advantages

• Very low surfactant concentration to work on mist reduction
• Lower product loss rate
• Less potential for interference with SX-EW circuit

Benefits

• Reduced tankhouse sulfuric acid mist levels
• Reduced structural corrosion
• Does not increase phase disengagement times
• Does not adversely affect copper extraction kinetics
• Cost effective electrowinning process
• Improved work environment

Typical Applications

• Copper electrowinning applications
