Heterosteric stabilization and selective flocculation

Journal of Colloid and Interface Science, 1978
Abstract It has been found experimentally that the mixing of dispersions of particles, sterically stabilized by different stabilizing moieties, may result either in heterosteric stabilization or in heteroflocculation. The theory for heterosteric stabilization and flocculation in dispersion media composed of low molecular weight species is therefore ...

FLOCCULATION OF SELECTED CLAYS BY VARIOUS ELECTROLYTES

Clays and clay minerals (National Conference on Clays and Clay Minerals), 1960
AbstractThe flocculation behavior of clay specimens from altered basalt, altered granodiorite, and a transported (?) deposit in Latah County, Idaho, was investigated in order to determine if flocculation behavior would be an aid in characterizing clay samples in a way that could be related to the origin and history of the clays.

Enhanced selectivity of polymer adsorption in selective flocculation

Mining, Metallurgy & Exploration, 1992
In the selective flocculation process, polymers with specific functional groups can yield highly selective adsorption and, therefore, high separation efficiency. Selectivity in polymer adsorption may also be attained by specific additives that inhibit the adsorption of the flocculant on some solid surfaces but not on others.

Fine Coal Cleaning by Selective Flocculation

Coal Preparation, 1992
A mathematical model was developed for coal-coal pyrite separation by selective flocculation technology. The model predicted that selectivity is primarily governed by polymer adsorption, although improvements in selectivity may also be obtained by controlling the polymer dosage when the selectivity in polymer adsorption is not very high.

Competitive yeast fermentation with selective flocculation and recycle

Biotechnology and Bioengineering, 1989
AbstractContinuous fermentations were carried out involving competition between two strains of Saccharomyces cerevisiae. One of the strains has a lower specific growth rate and is very flocculent, whereas the fastergrowing strain is nonflocculent. The product stream from the chemostat was fed into an inclined settler where the flocculent strain was ...

Flocculation, filtration and selective flocculation studies on haematite ore fines using starch

Minerals Engineering, 1991
The flocculation and filtration characteristics of typical Indian iron ore fines have been studied using starch as flocculant in the presence of an inorganic electrolyte, namely calcium chloride. The effect of various parameters such as pH, starch and calcium chloride concentrations and pulp density on the settling and filtration rates, turbidity of ...

Beneficiation of diasporic-bauxite ore by selective flocculation with a polyacrylate flocculant

Minerals Engineering, 2008
Abstract Beneficiation of a diasporic-bauxite ore by selective flocculation with sodium polyacrylate (PAS) was studied. Flocculation behaviors of diaspore, kaolinite, illite and pyrophyllite in the presence of PAS were also investigated by sedimentation tests.

Scientific design of a selective flocculation process

Mining, Metallurgy & Exploration, 1993
Selective-flocculation process development generally involves single-mineral flocculation tests to identify the appropriate polymer and experimental conditions for achieving the desired selectivity. Invariably the selectivity predicted on the basis of such tests is not realized when mixed-mineral tests are conducted.

Loss of selectivity in apatite-dolomite flocculation

Mining, Metallurgy & Exploration, 1987
Lack of selectivity in mixed mineral flocculation can be attributed to one or more of the following factors: dissolved ion interference, heterocoagulation, mechanical entrapment in flocs, and entrainment of fines between flocs. In a study of the apatite-dolomite system, it was determined that dissolved ions do not have a significant effect on ...

Fine Particle Separation by Selective Flocculation

Separation Science and Technology, 1982
Abstract One of the most promising techniques for separating very small particulates is selective flocculation. A number of successful applications for selective flocculation have been demonstrated on laboratory and pilot-plant testing, but with only a few commercial applications.
