Thickener performance optimized with upgrade, service and support

A gold mine was experiencing ongoing problems with froth formation on its preleach thickener. Feeds with entrained air are a challenge to the thickener flocculation process. Aerated thickener feed that makes its way into the body of the thickener tends to carry fine particles to the thickener surface to form froth.

The roasting cost works out at approximately per ton of concentrate, distributed as shown in Table 99. At MacLeod Cockshutt Gold Mines, Ltd., the cost of roasting in 1941 1942 was 32 cents per ton milled or per ton of ore roasted, while at Lake Shore mines for the same year the cost was about 80 cents per ton roasted.

Major Mines Projects | Ahafo Mine

The undersize of the trash screens reports to the 42 m Ø preleach thickener with the thickener overflow recycled to the milling circuit as process water. The preleach thickener underflow is pumped to CIL leach and adsorption tanks in series. Carbon is added to the CIL tanks and flow countercurrent to the process slurry.

Tailings Management With Paste Thickening

The floated material from the flotation process is also sent to the tailings thickener. The underflow from the flotation process is sent to the concentrate thickener. In the concentrate thickener, the purified slurry is thickened prior to being pumped to a disc filter. Again, the addition of polymer aids in the separation and thickening process.

The geotechnical testwork identified a target moisture of 15% (process definition). The slurry feed concentration is 40% m (process definition) which corresponds with the last stage of the carboninleach (CIL) circuit of the process plant. Prethickening was not considered. The cake thickness tested was 30 mm (equivalent).
