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

2003-3-10  liberate coal from pyrite and other ash-forming impurities. 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.

Flotation Tests with Homemade Flotation Equipment

2016-7-11  Such a filter can be placed under the froth-discharge of a flotation machine so that a fairly dry cake of concentrate is ready for further drying at the end of the flotation test. By loosening the outer rim of the filter-paper and then turning the funnel upside down over a pan, the filter-paper with the concentrate can be dropped into the drying-pan by gently blowing into the stem of the funnel.

Dry Grinding SpringerLink

Among the raw materials thus treated are asbestos rock and “crudy”, coal for powdered fuel, cement clinker, talc, metal powders, drugs, and chemical salts. In addition to open and closed-circuit grinding, batch treatment is frequently used. In this method, grinding media and feed are loaded into the grinding mill and worked dry until the desired state of attrition has been achieved. The product is then discharged.

Decrease of particle size by dry grinding affects the thermal behavior of pyrophyllite and decreases the starting temperatures of weight loss. Grinding also produces a disruption of the 2:1 structure giving an exothermic effect at $1000°C, mainly due to mullite formation, and decreases the intensity of the Si-O stretching vibrations.
