PROJECT ECONOMICS To be of value for any project the fundamental characteristics of a flotation machine must translate into actual economical benefits. Common measures are capital, operating and maintenance costs.

CiteSeerX — AN IN-PLANT EVALUATION OF FROTH

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Column flotation cells have become increasingly popular in the coal industry due to their ability to improve flotation selectivity. The improvement can be largely attributed to the use of froth washing, which minimizes the nonselective entrainment of ultrafine minerals matter into the froth product.

Effect of microemulsified collector on froth flotation of coal

2013-12-9  Froth flotation is a fine particle separation process, based on the difference in surface hydrophobicity of different components. It is often very effective for coal cleaning, since coal is naturally hydrophobic and minerals are generally hydrophilic. Because of coal’s hydrophobicity, froth flotation has employed mostly non-polar

2021-5-7  Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.
