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.

Prom that point it is pumped to the filter. The excess water that is not wanted in the concentrate is allowed to flow over the side of the thickener in a controlled manner. It is then either reused in the circuit or is sent to tailings. That is simplest explanation I know of as to the workings of a thickener and its operation.

What Are Gold Tailings. To be shortly saying, tailings are ground up rock minus the gold. The placer or rocks mined from underground which contains gold is called ore. The gold mining process involves crushing the ore into sand and dust to liberate and recover the gold. What's leftover is called tailings.
