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.
