REASONABLE REDUCTION IN HYDROPHOBY OF MINERAL SURFACE ON FLOTATION BY CARBOXYLIC ACIDS

摘要

Numerical estimation of the effect of surfactants on floatability of particles with different wettability is reported. It is proved that the particles with higher hydrophilic surface are recovered into a froth product at the "gas - pulp" interface at the presence of a film of normal alcohols and fat acids. Theoretical value of the suppression coefficient for the capillary wave amplitude coincides satisfactorily with the test values and may be used in calculations.
