    How a Thickener Works Mineral Processing & Metallurgy

    How a Thickener Works Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat bottomed tanks into which the pulp was fed until the tank was full.
