A Comprehensive Guide to the Operation of Thickener
1. Gravity Settling. Mining thickeners rely on the force of gravity to promote the settling of solid particles within the thickener tank. When the ore slurry enters the tank through the feedwell, the solid particles, heavier than the liquid phase, start to settle under the influence of gravity. 2. Hindered Settling
Thickening
Thickening Definition Continuous thickening by an operation called sedimentation is the separation of suspended solid particles from a liquid stream by gravity settling. The primary purpose of thickening is to increase the solids concentration of the feed stream. Gravity settling is aided by addition of chemicals called flocculants.

Solid – Liquid Separation – Thickening
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.
Types of Thickeners in Mineral Processing
There are 4 types of thickeners in mineral processing plants: rake thickener, efficient thickener, tilted plate thickener and deep cone thickener.
Beginners guide to thickeners
Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in phase densities drive the separation of the solids and liquid.
