  • How a Thickener Works Mineral Processing amp; Metallurgy

    How a Thickener Works. Previous Next. 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. ENTER our Mining

  • Difference Between Clarifier and Thickener

    The Difference Between a Clarifier and a Thickener is subtle as they will visually look the same. Fundamentally, thickeners and clarifiers are both used to settle solids which results in the separation of liquids and solids.
