ABSTRACT:
The present invention relates to compositions useful for the suppression of fugitive dust emissions and methods of suppressing dust emissions by application of an aqueous solution comprising a surfactant, wetting agent and an acrylic copolymer. The compositions of the invention are effective in wetting, penetrating and improving particle cohesion and reducing water evaporation. They can also be used as a knockdown agent for airborne dust and for minimizing soil and dust erosion, blowing and loss from roads and bulk solids, mineral flotation processes, waste management applications and as a binding agent.
