Thickener - an overview ScienceDirect Topics

Although deep cone thickeners are relatively cheap to install and occupy a small floor area, their operating costs can be higher. The flocculants required to promote efficient settling and operation are generally expensive, and high power inputs may be needed to maintain the stirring action of the paddle through pastes that are characteristic of the high viscosity underflows.

Design and Operation of the Kupol Project Counter

Kinross Gold’s Kupol Mine elected to use deep cone thickeners for their counter-current decantation (CCD) circuit as well as the grind thickener. Deep cone thickeners are commonly used for CCD circuits in the alumina industry, but this is the first application of that outside of alumina. The project started with process testing and proceeded through design, construction and startup. The circuit design incorporated both mechanical and process challenges. Using deep cone thickening allowed the CCD circuit to be installed indoors which was necessary in the arctic environment at Kupol. The deep cone thickener

However, for the mine backfill opera-tion, some thickeners are designed as both dewatering device and storage tank, which means they cannot discharge continuously. There is a growing body of evidence showing that shearing a con-solidating bed, as in the case in a raked thickener, vastly improves dewaterability.
