formed when water is released in the flotation cell at atmospheric pressure. The influent feed stream may be pressurized by means of a pressurizing pump to 172-620 kPa with compressed air added at the pump suction. The pressurized stream is held in a retention tank at this high pressure for about 0.5 to 30 min to allow sufficient time for the ...

at design time. Machine learning methods can be used for on-the-job improvement of existing machine designs. The amount of knowledge available about certain tasks might be too large for explicit encoding by humans. Machines that learn this knowledge gradually might be able to capture more of it than humans would want to write down.

For a testwork laboratory treating a wide variety of ores, the most useful laboratory flotation machine is probably one with cells of 500, 1000 and 2000g capacities, with a different diameter impeller for each cell, with stainless steel or rubber-covered impellers, glass or plastic cell bodies, and requiring an outside source of low-pressure air.

Jan 04, 2012· There are a number of standard laboratory flotation machines and cell sizes. The Denver D1 and D12 machines are the most commonly used (Figure 1) and come with a variety of cell and rotor/stator sizes from 1.5 to 8.0 l. (Figure 2). Tests using the 8.0 l cell require a larger rotor/stator.
