The Denver DR flotation machine, which is an example of a typical froth flotation unit used in the mining industry, is illustrated in Figure 1.47. The pulp is introduced through a feed box and is distributed over the entire width of the first cell. Circulation of the pulp through each cell is such that, as the pulp comes into contact with the impeller, it is …

Specifications Sizes: 100 cu.ft./cell – 600 cu.ft./cell (open flow) = from 2.82 cubic metres to 17 cubic metre Sizes: 100 cu.ft./cell – 300 cu.ft./cell (cell-to-cell) = from 2.82 cubic …
Thirty years ago, a cell 30 cubic metres in volume would have been unusually large. Now, 300-cubic-metre cells are commonplace. Outotec has a 500-cubic-metre cell in operation and several 630-cubic-metre cells in delivery, while FLSmidth has one 660-cubic-metre cell in operation. Building one big tank does provide energy economies of scale.

Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry, the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,, and pumped down the
Above are illustrations of three Flotation cells. 14.2 m3 (500 cu.ft) cell 2.8 m3 (100 cu.ft) cell 1.4 m3 (50 cu.ft) cell Note the nominal depth (A) of the flotation separation zone in all the cells is the same in each case. Intense agitation and aeration occur in the mixing zone at the bottom of the cell. This mixing or vertical recirculation

Agitair, Denver or Wemco. For a test work laboratory treating a wide variety of ores, the most useful laboratory ßotation machine is probably one with cells of 500, 1000 and 2000 g capacities, with a different diameter impeller for each cell, with stainless steel or rubber covered impellers, glass or plastic cell bodies, and
In the plants, flotation takes place in circuits, in which the flotation cells are arranged into banks of cells to obtain the desired final recovery and grade. If the recovery of minerals in individual cells is R, then overall recovery of the first cell is R, and the fractional feed entering the second cell is 1 − R.
