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.John Frank
The thickening equipment of gold cyanide factory adopted hydraulic motor driving center thickener, the capacity does not meet expected goals, and the timing of rake lost working hours, the working efficiency is low. On this basis, the client increased two improved hydraulic motor driving center thickener. Hydraulic type.
HRT Control System at Sunrise Dam Gold Mine. The control system installed in the SDGM thickener is shown in fig. 2 where the underflow density is controlled by a bed mass pressure probe and the flocculation rates controlled by a bed level probe. The control strategy based on bed mass is explained below. Solid Mass.

Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to 'see' the gold in the leaching process. The remaining slurry passes through a pre-leach thickener (11),.
The Ok Tedi mine, operated by Ok Tedi Mining Limited (OTML), is a major producer of copper concentrate for the world's smelting market, yielding some 600,000 tonnes of high-grade copper concentrate a year and 500,000oz of gold. The mine is located on Mount Fubilan, Western Province of PNG, with an altitude of.
Application Problem: The customer at a large Gold/Copper mining company wanted to improve the automation control of it's CCD circuit of five thickeners. The problem was inconsistency of the floc dosing chemical to the CCD circuit which was causing settling prob- lem in each thickener. This problem increased as different.
A vacuum disc filter, preceded by a high-rate thickener to reduce the hydraulic loading, is typically used to produce the “sludge” portion of the mine backfill. The filter cake is discharged to a weigh hopper, then to a batch mixing hopper or a continuous mixer where a measured amount of binder and other materials are added.

Research at the Porgera Gold Mine is focusing on developing a method of combining tailings products with coarse waste rock and waste muds to create a product that can be stored on the surface in generic-looking waste dumps or stockpiles. This would allow the current use of rivering disposal to cease. Considerable work.
