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.
Thickener Capacity: 5 400 t/24h Application: Thickener is suitable for the dewatering process of concentrates and tailings in the mineral processing plant, and is widely used in the metallurgy, chemical, coal, non metal ore dressing, environmental protection and other industries.
a homogeneous product and to avoid local thickening. High shear mixing is recommended for the best results. Problems can arise if the stirrer is too slow or too small and does not move the total batch . Texipol is shear stable,
The Dorr traction thickener is the type most frequently used for heavy duty work with large tonnages. The machine is so called because the thickening mechanism is driven by means of a traction wheel which travels around the periphery of the tank on a rail.
A thickener has several basic components: a tank to contain the slurry, feed piping and a feed well to allow the feed stream to enter the tank, a rotating rake mechanism to assist in moving the concentrated solids to the withdrawal points, an underflow solids withdrawal system, and an overflow launder.

How to Operate a Thickener Mineral Processing amp; Metallurgy In operation, the tank is full of whatever it is you are thickening, usually a pulp of ground ore, or tailing, and water. The liquid overflows around the edge of the tank, and the solids, also called the slime or the sludge, settle to the bottom of the tank.

Depressants inhibit the flotation of one mineral or minerals while activators enable the flotation of others. Examples of these include CN , used to depress all sulfides but galena and this depressant is believed to operate by changing the solubility of chemisorbed and physisorbed collectors on sulfides. This theory originates from Russia.
