Nov 06, 2017· The tailings are thickened at the mill in a high rate thickener before being pumped to the storage facility by a train of centrifugal slurry pumps. The design considered the following key issues: The optimum design concentration to increase the tailings concentration, while maintaining reasonable capital costs for the system
May 01, 2015· Above image: Mine tailings are the ore waste of mines and are typically a mudlike material. The storage and handling of tailings are a major environmental issue. Shown is the traction thickener at Khumani. Mine tailings disposal, and its impact on water usage, is an important concern for any mining company.

Ore processing consists of the following stages: crushing and grinding of the ore; addition of process water (generally decanted from the tailings pond) to form a slurry; addition of lime to the ore, and cyanide solution to the slurry, to leach the gold and silver into solution
The objective of this chapter is to present a literature review of tailings dam design and construction in general, as well as a critical review of the engineering properties of gold tailings.

A new thickener was designed and installed to thicken the tailings and rheological testing of the tailings, using a closed loop pilot plant, provided parameters to upgrade the underground reticulation system to deliver cemented backfill to stopes throughout the mine and to deliver thickened tailings to the TSF. The revised design was ...
Their leach feed thickener was creating a bottleneck in their processing plant. The thickener – which was neither supplied nor installed by FL — was an offtheshelf design. It was not optimised for the plant or the processing requirements, and was hindering the gold mine's success.
This mixture, called fluid fine tailings can take decades to form a solid, if left on its own. Industry researchers have developed a suite of tailings thickeners that help solidify the residue. However, the thickened tailings have the consistency of thick mud and thus, require different design .
The particular design of these retaining structures is unique to a particular environment and mineral processing operation. When considering the design of a tailings storage facility there are many parameters which impact on the optimum site selected and the storage and tailings discharge methods used (Ritcey 1989).
