Froth flotation - Wikipedia

04/03/2005  Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the ...

Table 1: Grade/recovery performance of a hypothetical copper ore flotation process. Product % Weight % Cu Assay Feed 100 2.09 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 ...

11.21 Phosphate Rock Processing

20 mesh is treated by 2-stage flotation. The flotation process uses hydrophilic or hydrophobic chemical reagents with aeration to separate suspended particles. Phosphate rock mined in North Carolina does not contain pebble rock. In processing this type of phosphate, 10-mesh screens are used. Like Florida rock, the fraction that is less than 10 mesh is treated by 2-stage flotation, and the ...

On the Phosphate Rock Beneficiation for the

01/01/1992  For grinding phosphate rock, the energy used is about 25-35 MJ per tonne and the process water needed is around 13 m3 per tonne while the average values for ore flotation units are 62.5 MJ per tonne and 5.3 m3 per ton for energy and water use, respectively. So far the challenge in the flotation of high carbonate containing sedimentary phosphate rock has been to find the method
