Effect of Wet Versus Dry Grinding on Rejection of Pyrite ...

Froth flotation is the most commonly used technique for beneficiating fine coal. Since the mode of grinding, dry or wet, can affect differently the surface properties of coal and the gangue minerals it is important to understand its role in the flotation process.

Ash Depression in Fine Coal Flotation Using a Novel ...

However, the coal flotation process has been challeng-ing, problematic and costly due to the slime coating of colloidal mineral matter on the surfaces of coal particles and air bubbles. These slime coatings likely reduce the effec- tiveness of flotation recovery, especially when fine grinding is required. Slimes inhibit bubble-particle attachment and increase reagent consumption due to an ...

So grinding of oxidized bituminous coal might deteriorate flotation performance due to the increase of ultra-fine particles. In addition, the grinding process is usually at a high temperature (Hadad and Sadeghi, 2012). In this condition, coal samples might be re-oxidized especially for lower rank coals (Wang et al., 2003, Zhang, 2004).
