Concentrate 10 20.0 Tailings 90 0.1 (a) From Table 1, the Ratio of Concentration can be calculated as F/C = 100/10 = 10. If only assays are available, the ratio of concentration equals (20 – 0.1)/(2.09 – 0.1) = 10 So, for each 10 tons of feed, the plant would produce 1 ton of concentrate.

In principle, the cell functions as a shallow flotation cell. As the air and pulp are hydrau-lically lifted to the top of the pulp recircula-tion well, the mineral laden air bubble has only to travel a short distance on its own to the froth overflow level. Above are illustrations of three flotation cells. 14.2 m3 (500 cu.ft) cell 2.8 m3 (100 cu ...

Section snippets Background. The flotation kinetics test remains the workhorse of flotation circuit design and scale-up. The test is conducted by putting a known mass of sample in a laboratory flotation cell with water and reagents and adding air and agitation for fixed time intervals, over which concentrate samples are collected.

A standard 5L Denver flotation cell was used. Air was controlled at 10 l/min, yielding an approximate superficial gas velocity (J g) of 0.5 cm/s. Lime was added to maintain constant pulp pH throughout the test and pulp oxidation–reduction potential was measured and recorded but not controlled. The impeller speed was fixed at 1300 rpm.

The effect of impeller speed on the air flow in a self-aerated Denver laboratory flotation cell was investigated using computational modelling.Air is induced into the slurry by the impeller's rotating action. The rate of air flow is determined by the suction pressure created by the impeller, the hydrostatic head of the slurry and the frictional …
