Mineral flotation is a process whereby valuable hydrophobic mineral particles are recovered
from low grade mineral pulp by means of attachment to air bubbles. Particles smaller than …

In order to study the effect of frothers on the size of bubbles, experiments were carried out
using single-and multi-hole spargers and a flotation cell. It was found that the size of bubbles …

In mineral flotation, surface loading dynamics of bubbles due to particle attachment and
detachment in a turbulent environment is central to the understanding of separation kinetics …

The depression of pyrite in sulfide flotation by two types of polysaccharides, CMC and guar,
was investigated using micro-flotation tests, zeta potential measurements and adsorption …

Polysaccharide reagents are frequently used in the mineral processing industry to improve
the grade of the concentrate by depressing the naturally floatable gangue. A microflotation …

Surfactin, a biosurfactant, has the potential to replace synthetic surfactants in froth flotation.
This research investigates the surface interactions between surfactin and coal which …

Sulphoxy anions in recycled flotation process waters possess the potential to reduce the
flotation efficacy of flotation reagents. In this study, dithionite ions and their interaction with …

The drive towards cost-effective and environmentally friendly reagents has led to a
significant increase in investigations into microorganisms and metabolites as potential …

The non-stoichiometric sulfide mineral pyrrhotite (Fe (1− x) S), common to many nickel ore
deposits, occurs in different crystallographic forms and compositions. A series of pyrrhotite …

Abstract Analysis of bubble–particle mechanism is important for improving our
understanding of flotation process. The research presented integrates microflotation …
