to depress gangue, and float concentrate. Typically, flotation is practised between the limits 6') mesh and 51-" This is quite apart from any consideration of "break" or of liberation mesh. Flotation is not concerned to alter the chemical nature of the particles involved, but to modify their surfaces. Most freshly exposed mineral
— 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.

— Instead, froth flotation has been demonstrated as the most effective method. This work provides a literature review on the current state of barite in terms resource type, production and processing via froth flotation. Also suggested is that new barite resources need to be explored to meet the upcoming demand.
To achieve selective flotation of mineral particles, whether by their removal in a froth or by the less-used method of agglomeration, specific characteristics of one or more of the mineral species present must be adequately developed. Provided these produce...
