Contact angles of quartz particles were calculated from the ratios of particle wetting rates of water (polar) and toluene (non-polar) through compact particle beds, contained in capillaries (capillary penetration of liquids). For comparison, the cont

Grinding and flotation experiments on a Pb-Zn ore were carried out to evaluate: 1) wear of the grinding media both in the presence and absence of an inhibitor and 2) effect of the inhibitor on the flotation of PbZn minerals. The percentage reducti

In the treatment of sulphide ores, the reactions occurring in several processes like wet grinding, flotation, collectorless flotation, leaching/bioleaching and in adsorption mechanisms, for example the interaction of thiol collectors with oxidation-r

The present work deals with the shear-flocculation of quartz in aqueous solutions of dodecylamine chloride. The variables studied include pH, concentration of the amine, size of the coarse particles, stirring speed and time. The zeta potentials were

Shear-flocculation/flotation and carrier flotation are methods by which fine mineral values are aggregated and then recovered by flotation. The aggregates formed have better floatabilities. Without prior treatment ahead of flotation, significant quan
Capillary penetration techniques were used to determine the wettability of sphalerite particles under flotation related conditions. Particle contact angles were determined separately from measurements of wetting rates (Washburn technique) and equilib

Like froth flotation the shear flocculation is governed by the physical, chemical and geometrical variables. Among the important factors which influence the particle aggregation are the particle size, hydrophobicity, charge and the intensity of agita
