the impossibility of direct production of hematite concentrate by flotation or magnetic separation. The gravity concentration allows obtaining of iron concentrate from the wellprepared feed (size fraction 53+20 micron) but with very low recovery. Thus, the hematite concentrates with weak silica content and satisfactory iron recovery were obtained by reverse ionic flotation, when it was ...

AkzoNobel Surface Chemistry
In hematite flotation, the most normal case is to float fully liberated quartz from hematite. AkzoNobel collectors are used to produce highgrade concentrates for iron ore pellet production. They can also be used for the production of superconcentrates for advanced metallurgical appliions. Flotation of phosphate/apatite . The processing of phosphate ores is often a straightforward and ...

flotation hematite ore concentrate
Flotation testing on a specular hematite ore containing 40 per cent Fe and per cent silica gave highest iron grades in concentrate at pH 6, in contrast to published data which suggested pH 9 as the optimum value for ore processing. Using octyl hydroxamate, a rougher concentrate assaying 67 per cent Fe at 51 per cent recovery was obtained

In this ore, hematite and quartz are present as the major mineral phases where goethite, martite, and magnetite are present in small amounts. The liberation of hematite particles can be enhanced to about 82% by reducing the particle size to below 63 μm. The rejection of silica particles can be obtained by magnetic and flotation separation techniques. Overall, the BHQ ore can be enriched to 65 ...
