Physical and chemical interactions in coal flotation ...

29-09-2003  Coal flotation is a complex process involving several phases (particles, oil droplets and air bubbles). These phases simultaneously interact with each other and with other species such as the molecules of a promoting reagent and dissolved ions in water. The physical and chemical interactions determine the outcome of the flotation process.

Effect of microemulsified collector on froth flotation of coal

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
