Sludge treatment − gravity thickening | Sludge Processing

 · Gravity thickeners generally retain 80−90% of the solids in the thickened product stream, depending on the sludge characteristics and the efficiency of the preceding conditioning stage. The sludge characteristics also govern the solids loading rate (SLR), which is the rate in kg/d at which the sludge dry solids enter the process per unit process cross-sectional area.

Optimization of dewatering systems for mineral processing

 · At this stage, the mineral is mixed with water and wet milled to an optimal granulometry to achieve flotation. The flotation process yields two products, a concentrate and tail streams, that are sent to dewatering systems for water recovery. These systems usually include thickeners, hydrocyclones, and filters.

Thickener technology for mineral processing – CSIROpedia

 · To start with, mineral thickener works on the principle of Gravity sedimentation and the most common construction of a thickener would be of iron or steel. The continuous thickener consists of a cylindrical tank. Pulp is fed into the centre of the tank via a feed-well placed up to 1 m below the surface of the suspension.

Mineral processing

Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.

Solid – Liquid Separation – Thickening

 · The separation of solids from liquids is usually achieved by gravity sedimentation in thickeners. For fine particles this is a slow process. In general, 75–80 % of the water can be separated and removed by thickeners. For further water removal, filters are used where in excess of 90% of the water can be removed.
