How a Thickener Works - Mineral Processing & Metallurgy

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. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were ...

Decantation Definition in Chemistry - ThoughtCo

In its simplest form, it just means allowing a mixture of solid and liquid or two immiscible liquids to settle and separate by gravity.
