Froth Flotation Handbook
— Froth-flotation is in general effective only on ores ground to pass 0.3-mm. aperture or less and the agitation-froth and bubble-column processes are most effectively practiced when the bulk of the feed will pass a 0.074-mm. screen. In these latter processes the finely pulverized ore must be in the condition of a freely flowing pulp with water.
