Thickener Optimization in your mining process | Endress+Hauser

The thickening process is a fundamental step in modern mining separation processes. Thickening is the separation of suspended particles from a liquid by gravity settling. For effective thickener control, six measurements are critical: bed mass inventory, bed level, underflow density and flow, flocculent dosing and overflow clarity.

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 ...
