The question of why are we grinding to some target grind how efficient should that grinding be do we care if we generate excessive 10 um particles is not being asked For a flotation process have we really understood the whole liberation versus recovery and optimization between primary and regrind...

Grinding media type is a critical factor in determining the chemistry of the flotation feed pulp and yet is infrequently studied in this regard by plant operators The normal operating philosophy is to choose the grinding media which produces the correct grind at m i n i m u m economic cost and adjust the chemistry by reagents andor aerationGet Price
Metallurgical ContentSURFACE TENSIONBULKOILOIL AND AIRBUBBLESCOAGULATIONFROTH Flotation in its latest phase is a process of concentrating ores by frothing When crushed ore previously mixed with water and a relatively minute addition of oil is agitated violently in the presence of air a froth is formed This froth rising to the surface of the liquid mixture is laden with sulphides orGet Price
The mineralogical character of the ore determines also the extent to which grinding must be carried before flotation is applied This matter has been previously discussed In the agitationfroth process the recoverable mineral content of an ore the amount of a given oil necessary the percentage of solids in the pulp treated the grade of concentrate and the recovery attained are strictlyGet Price
