Reverse flotation for removal of silicates from
2004-1-1 Kaolinite, pyrophyllite, illite and chlorite are the main gangue minerals in the diasporic-bauxite ores, these aluminum-silicate minerals affecting reverse flotation de-silicating, as the floatabilities of the three aluminum-silicates are different (pyrophyllite > kaolinite ≈ illite). In this work, two different samples (samples I and II) having different compositions of aluminum-silicate minerals were used in the

FLOTATION OF SILICATES FROM ORES - Akzo Nobel
Silicate-containing minerals are generally removed from flotation systems by using reverse flotation technique whereby the silicates are floated in a pH range from natural pH to 10.5-11 and the beneficiated ore is concentrated in the bottom fraction.

Froth Flotation of Iron Ores
2012-1-2 Kaolinite removal in iron ore flotation mainly involves three interactions, i.e. collector-kaolinite interactions, depressant-kaolinite interactions, and dispersant-kaolinite interactions. For collector-kaolinite interactions, it was found that the flotation behavior of kaolinite is opposite to that of silica.

Two-stage reverse flotation process for removal of ...
2018-10-6 Phosphate rock contains various gangue minerals including silicates and carbonates which need to be reduced in content in order to meet the requirements of the phosphate industry. Froth flotation has become an integral part of phosphate concentration process. In this study, double reverse flotation was applied to recover apatite from phosphate ore. H3PO4 and CaO were used as phosphate ...

Froth Flotation of Iron Ores - Publications
silica removal has been studied extensively, while alumina removal has received limited attention. The reverse cationic flotation route widely used in the iron ore industry is less selective for alumina/hematite separation than for quartz/hematite separation. Das et al.[28] studied the beneficiation of some alumina-rich iron ores and reported

2019-5-25 Process aids are generally required to improve bitumen recovery from poor-processing oil sand ores containing a relatively high amount of divalent metal ions and fine solids/clays. In this paper, the role of acidified sodium silicates as a dispersant/depressant of clay fines in bitumen extraction was evaluated using a laboratory hydrotransport extraction system (LHES) at low temperature (35 °C).
