To be able to remove impurities inside coal particle, reverse flotation is applied on coal. In reverse flotation, tailing is taken as clean coal, and concentrate is accepted as gangue minerals. Ash content is crucial for coal flotation efficiency.
[Process Introduction] Magnesite Flotation Process- Crushing and Grinding Process. Crushing: raw ore (less than 200mm) go through the two stages one close circuit process, which include jaw crusher and vibrating screen.And then broken to 10~0mm. Grinding: the crushed ore will closed-circuit grinding, in which ore will be ground to -200mm 70%, then into flotation process;

Reverse Flotation in Muş Elmakaya Lignite Beneficiation . nbsp 0183 32 Preliminary flotation studies showed that gangue minerals were floated instead of the lignite sample in the flotation medium For this purpose the effects of some parameters that markedly influence the effectiveness of reverse flotation such as grinding time solid concentration pH collector type …
2.Grinding and Grading Stage. Grinding and grading stage is very important for flotation process. Grinding fineness is an important factor affecting the separation index and appropriate grinding can effectively dissociate target minerals and gangue minerals. Put the crushed ore with size less than 10mm into the ball mill for monomer dissociation.

The grinding time has considerable effect on particle morphology that while the particles ground for 2 min exhibit 0.793 roundness and 23 nm average roughness value, it gradually changed to 0.809 roundness and 57 nm average roughness value upon 16 min grinding.-The flotation kinetics studies showed that while lower flotation constant values ...
Flotation is one of the most effective technologies for the up-gradation of coal fines of particle size below 0.5 mm because of the inherent hydrophobic nature of coal.Contrary to this, reverse flotation of coal in which coal particles are depressed and gangue particles floated, was developed as an alternative process to minimise the sulphur content in the coal.
