Roles Of Surfactants In Ore Flotation

In general surfactants play three roles in flotation deinking (1 4) a) as a dispersant to separate the ink particles from the fiber surface and prevent the redeposition of separated particles on fibers during flotation deinking Page 41 Recycling 101

    Surfactants & Mine Dust Control & Effect On Flotation

    Dust measurements in mines clearly indicated that the major mineral dust exposure is due to loading and transport of the ore from the mining areas One approach to the solution of this dust problem is the application of water sprays to reduce dust dispersion Wetting of broken rock is very effective in preventing fine dust from becoming airborne by binding it to the larger lumps
