How to Operate a Thickener

The simplest use of a thickener in a metal-mining operation is to get water out of a pulp; for example, in a desert country where water is too valuable to be thrown away with the tailings. There you have a thickener treating the tailings and recovering some of the water to be sent back to the mill and used over again.
