In most of the mining operations, a process is used to separate the values of the tailings, or in the other case to separate the concentrate from the water in both procedures this happen in an equipment called thickener, in this article we will see in a simple way, its parts and the control parameters for its proper functioning.
The parts of a thickener are the following:
Regarding its operation, the thickener has 3 distinctive zones:
Having said that, we now can comment on the main objectives of thickening, such as having a continuous and adequate feed, that the overflow is as clean as possible, and that the thickened product has the density required at the time of discharge.
In order to achieve these objectives, a series of measurements are necessary, from the height of the rake level, to the density of the solids in discharge, which allow us to optimize the entire thickening process.
