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 .

ANDRITZ SEPARATION - PowerDrain gravity belt 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 Thickeners are used to concentrate solids, while clarifiers are used to purify liquids A thickener will give you a high density underflow while a clarifier will not
Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: ie the components of the mixture have different specific weight All of the gravitational methods are common in the sense that they all use gravity as the dominant force
