Concentrate Thickener Operation
The thickener is a very basic piece of machinery that performs its job in an easily understood manner. It simply provides a holding area large enough to allow the concentrate time to settle to the bottom. Once there, there are RAKES that rotate pulling all of the mineral to the center of the thickener. Prom that point it is pumped to the filter.
