Concentrate Thickener Operation - 911 Metallurgist

12-08-2015 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

Copper Flotation - 911 Metallurgist

16-05-2016 The flotation of native copper ores is nearly always preceded by gravity concentration in jigs and tables not only because the combined process is more economical as regards costs, but also because the copper often occurs as large grains which flatten out during grinding and cannot be broken to a size small enough for flotation.

cleaned in several flotation steps. After sedimentation in thickeners and filtration in automatic filter presses or vacuum filters (ceramic disk) the typical copper concentrate contains 25 – 35 % Cu and about 8 % moisture. The moisture content of the concentrate is a compromise between transporting

Copper Flotation - Elmhurst University

Ore Concentration by Froth Flotation. Remember that only 0.67% of the ore is copper. The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up limestone) to give a basic pH, pine oil (yes, it comes from trees -- a ...

Both the copper and moly sulfide ores together (bulk) float in rougher flotation cells, then cleaner column cells, and often scavenger cells. These groups of flotation cells work together to give a high total yield of the bulk ore, which is sent on to be thickened. Tailings (Gangue) Thickening / Dewatering.
