How to Operate a Thickener
If it is a tailings thickener, you are wasting water, which is unforgiveable in the desert. If it is a concentrate thickener, you . may be handing the filter operator a headache, which he may return with interest. If it is a C.C.D. thickener, you are only making trouble for yourself farther along the line.

Tailings Management With Paste Thickening
The floated material from the flotation process is also sent to the tailings thickener. The underflow from the flotation process is sent to the concentrate thickener. In the concentrate thickener, the purified slurry is thickened prior to being pumped to a disc filter. Again, the addition of polymer aids in the separation and thickening process.

Sludge treatment − gravity belt thickening
How gravity belt thickening works. Gravity belt thickening (GBT) increases the sludge solids concentration (i.e. thickens the sludge) by allowing the water (or filtrate) to drain from the sludge under gravity through a permeable medium (a moving belt) on which the sludge sits.. There are two types of belt-based processes for increasing …
