Why high-rate thickeners are now preferred by the gold

May 01, 1990 Typically, the capital cost of a conventional thickener (eg, 30m dia unit for a 500,OOOtpa gold treatment plant) would increase the cost of the treatment plant by 10-15%; the use of a high rate thickener (10m dia unit for 500,OOOtpa) would result in a 3-4% increase only in the plant cost and achieve the same water and cyanide recovery.

Concentrate Thickener Operation

In mining, when flotation is finished with the ore, and a final concentrate has been produced, often, both products will go to a concentrate thickener before it is dried for shipping. This is a very important step so here we discuss Basic Concentrate Thickener Operation. For the mine to get its concentrate to the smelter it will have to be transported, by truck, train or ship. To illustrate

Gold CIL process (carbon in leach) is an efficient method of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lowers the gold mining operation cost and increases gold recovery rate to 99%, which is the first choice of modern gold mining and gold beneficiation plant
