Learn more about 3M™ Acid Mist Suppressants

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
