Paste vs. Conventional. 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 percent solids Newtonian slurry in conventional or high-rate thickeners.
