3M™ Acid Mist Suppressant FC-1100 is a fluorochemical additive that provides outstanding sulfuric acid mist suppression in the copper electrowinning tankhouse without the formation of a stable foam blanket in the electrowinning cell. FC-1100 suppressant can significantly reduce tankhouse acid mist levels, with no adverse effects to either the solvent extraction or electrowinning process.
The FC-1100 fluorochemical surfactant has been used in the production of copper by hydrometallurgy for more than 20 years now as an effective means of point source emissions reduction in the suppression sulfuric acid mist in copper electrowinning tankhouses.
