Open Access Selective Flocculation of Banded Hematite ...
ore is feasible by selective flocculation. Keywords: BHQ ore, Selective flocculation, Potato starch, XRD, FTIR, SEM. INTRODUCTION Selective flocculation is a useful technique commonly used to enrich ultra fine mineral particles that respond poorly to conventional beneficiation techniques. The beneficiation techniques, such as gravity separation, magnetic separation,
Selective Flocculation of Banded Hematite Quartzite (BHQ) Ores
The recovery of fine hematite particles from banded hematite quartzite (BHQ) ore with potato starch has been investigated using selective flocculation. Microscopic features, coupled with x-ray...
Advances in selective flocculation technology for solid ...
Selective flocculation is a potential process for solid–solid separations in the fine particle size range. The critical barriers to further the commercial applications of this technique are loss in predicted single mineral selectivity in mixed mineral systems, extrapolation of mixed mineral selectivity to natural systems, and scale up from laboratory to plant.
Depressants and Flocculants in Iron Ore Beneficiation ...
Flocculation and Filtration. The use of starches as flocculants was investigated in three different areas: the flocculation of an iron oxide slime, the selective flocculation and partial upgrading of a ground oxidized taconite crude, and clarification tests on the supernatant water from magnetite-taconite tailings.
(PDF) Recovery of iron from iron ore slimes by selective ...
The beneficiation of iron ore slimes by selective flocculation was studied. Polyacrylamide (PAM) and guar gum were used as flocculant, along with sodium hexametaphosphate (SHMP) as a dispersant.

Selective Flocculation of Banded Hematite Quartzite (BHQ) Ores The Open Mineral Processing Journal, 2011, Volume 4 47 consists of hematite and quartz as the major minerals. Minor amounts of magnetite, goethite, limonite as well as kaolinite are also present in the sample. The microphotographs of BHQ sample are shown in Fig. (2).

SELECTIVE FLOCCULATION Flocculation is used for the removal of clays and gangue with the use of liquid reagents. The technique of flocculation can be used to separate visible sediments and materials and to treat colloids. A colloid is a solution which looks uniform, but actually consists of one or more components blended together.
Beneficiation of Synthetic Iron Ore Kaolinite Mixture ...
Non the less these can be beneficiated alternatively by the process of selective flocculation, which is defined as the selective agglomeration of the desired mineral in the form of floc using natural or synthetic flocculant and the undesired minerals remains suspended in the supernatant liquid.
US Patent for Beneficiation with selective flocculation ...
A process which uses selective flocculation with hydroxamates for the beneficiation of mixtures of mineral particles (such as kaolin clays). The increased selectivity of hydroxamates for certain mineral phases within kaolin clays and other mixtures of mineral particles improves the process over selective flocculation processes utilizing other activators.
Beneficiation of diasporic-bauxite ore by selective ...
The beneficiation of mixtures and diasporic-bauxite ore by selective flocculation can be done with Na 2 CO 3 and PAS at pH about 9–10, but it is sensitive to the content of kaolinite. For the beneficiation of diasporic-bauxite ore, a concentrate can be obtained with the Al 2 O 3 recovery of 87.0% and Al 2 O 3 /SiO 2 ratio of 8.9. (3)
