Overview of Tungsten Ore Flotation - Fodamon Machinery

02. Flotation process of tungsten ore. Ⅰ. Flotation machine process of Scheelite. Scheelite Flotation generally requires fine grinding to fully dissociate the mineral monomer; If the ore contains sulfide, xanthate can be used to float out in advance; If the sulfide content is small, scheelite and sulfide can be floated out with oleic acid, and then the mixed concentrate can be

REDESIGN OF INDUSTRIAL COLUMN FLOTATION

2020-9-25 · basic difference between ore and coal flotation is that for ores the entire tonnage is ground to flotation size, whereas for coal only the fine fraction (about 60 mesh x 0) not processed by gravity concentration is treated by flotation. In coal flotation, the differences in the wettability of coal (hydrophobic) and rock (hydrophilic) are exploited.
