Jul 13, 2016 How a Thickener Works. Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle ...

Apr 25, 2016 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.

May 15, 2020 Indian mining industries primarily depend upon high-grade fines mainly because of two factors, one is lack of beneficiation infrastructure and high cost of low-grade fines, the second one is lack of proper tail disposal system. Due to lapses in our policies, miners get better premium by selling high-grade fines over low-grade fines. This restricts the flow of low-grade fines into the market ...
