The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants. Flotation has now become the most widely used process for extracting many minerals from their ores. Schematic diagram of a flotation separation cell.
In their plant grinding is carried out in a Hardinge Ball Mill in closed circuit with a Dorr Classifier, and a Sub A Cell is employed as the flotation unit between the two, the pulp being maintained at a density of 65% solids. Under normal operating conditions 60 70% of the copper and 40% of the nickel are recovered in the grinding circuit.
The flotation machine has played an important part in this selective flotation practice. This is especially true of the cell to cell type of machine such as the Sub A, where the number of cells to treat different minerals may be changed rapidly from time to time as contents and type of ore may vary.
3.This iron ore slurry is pumped to the agitation tank. This iron ore slurry is finally pumped to the flotation machine with the fine sulfide ore going to froth flotation cells for recovery of iron. 4.In magnetite processing plant,the process of flotation separation is replaced by magnetic separation.
Flotation cell technology and circuit designan Anglo Platinum perspective by C.M. Rule* and A.K. Anyimadu* Synopsis Froth flotation is the primary mineral processing separation step employed in the beneficiation of PGM ore bodies. Anglo Platinum operates a significant portion of the total installed flotation capacity
buying iron ore grinding ball mill ore dressing plant. In the iron ore dressing plant in yunnan, ore hardness, the ore has a high hardness, and the client requires small grinding particle size in order to avoid over crushing, the client selected xinhai wet type grid ball mill in grinding process the grindin.

recovered by additional flotation. The pilot plant experimental scope included over 50 tests. A grade recovery curve for each stream was developed, as well as information on the effect of ore type, feed rate, wash water, air flow, collector and frother on the performance of the cell.
The decision having been reached to design a flotation circuit according to a certain scheme, it is necessary to provide for fluctuations in the flowrate and grade of ore to the plant. The simplest way of smoothing out grade fluctuations and of providing a smooth flow to the flotation plant is by interposing a large agitated storage tank between the grinding section and the flotation plant:
Figure 1 is a generalized diagram of a conventional copper flotation plant from the point where ore first enters the circuit to the production of concentrate and tailings. To prepare ore for the flotation process, run of mine ore, which may contain from about 2 to 5 percent water, by weight, when mined, is
