How a Thickener Works

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. The solids were then allowed to settle ...

Solid – Liquid Separation – Thickening - ScienceDirect

In the gold industry for instance, the rule of thumb is a tonne of water for a tonne of ore. This bulk of water has to be separated or reduced for down stream treatment for recovery of the mineral in the ore. The separation of solids from liquids is usually achieved by gravity sedimentation in thickeners. For fine particles this is a slow process.
