In this paper, a scheme of flotation frothers classification is presented. The scheme first indicates the physical system in which a frother is present and four of them i.e., pure state, aqueous solution, aqueous solution/gas system and aqueous solut

This paper presents the determination of a concentration at the minimum bubble velocity (CMV) for different types of frothers, such as straight and branched alkyl chain aliphatic alcohols, 1,ω-diols, poly(propylene glycol) and poly(ethylene glycol)

Zeta potential of coal particles and kinetics of flotation along with the maximum recovery after a long time of fractionated flotation of naturally hydrophobic coals, both as a function of pH, were investigated. Empirical relations between the 1st or

A relation between the kinetics of flotation and particle size is complex, therefore different flotation ranges for ultrafine, fine, medium and coarse particles, are usually considered. Our data on kinetics of froth flotation and particle size of met

In this work flotation and single bubble tests were conducted with high purity quartz in water and hexylamine solutions at different pHs. It was found that flotation kinetics and time of the three-phase contact (TPC) formation (tTPC) at the quartz su

The time of a single bubble attachment to a rough hydrophobic solid surface with contact angle greater than 90° in aqueous solutions at different frothers (n-octanol, α-terpineol and N-octyl-trimethylammonium bromide) in the concentration ranges of
