  • Tailings Paste Disposal – More Than Water Recovery

    Paste thickeners thicken tailings to higher underflow solids concentrations than conventional and high-rate thickeners. For example, a tailings stream in an iron ore application could be thickened to 45-50 solids in conventional or high-rate thickeners. Conversely, the same tailings stream could be thickened to 65-70 solids using a paste.
