Settling characteristics of ultrafine iron ore slimes
The slurry settling characteristics are the most important to design a thickener in process industries. In this work, the iron ore slurry from the screw classifier overflow was used for the settling study. It was observed that the original slurry exhibited a low settling velocity and a turbid supernatant during the settling process. Commercial …
How to Operate a Thickener
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. ... The simplest use of a thickener in a metal-mining operation is to get water out of ...
