Investigation of the reverse flotation of iron ore in ...

01/05/2020 · This suggests that the flotation of iron ore may be improved by operating at lower solids concentrations, by reducing fine hematite entrainment through lower water recoveries. Here, coarse quartz recovery remains relatively constant but hematite loss is reduced significantly. However, these are laboratory-scale findings and would need to be tested at an industrial-scale. Here, the availability ...

Hematite ore dressing develops the flotation process and the strong magnetic separation process. It is mainly to use the oxidized paraffin soap as the collector, and the magnetic separator with electromagnetic flat ring high intensity. But its separating technical indexes do not reach the satisfactory effect. After all these years of development, the power of science and technology is stronger ...

01/08/2019 · The addition of magnetite has likely two effects on the reverse flotation of iron ore. It acts as a depressant by hindering transfer of fine hematite into the froth. It also acts as a flocculant to aggregate fine hematite particles, and aggregates formulated do not coat easy the quartz surface through a sliming process Ma et al., 2011, Lima et al., 2016).

flotation, was investigated in the reverse flotation of hematite ore slimes. Flotation tests found that the iron recovery increased with the addition of magnetic seeds; the depressing ability of starch in flotation was further enhanced by the MSD. The increased adsorption density of starch on target mineral hematite and apparent size enlargement of fine minerals are two reasons for the MSD ...

Hematite Processing by Flotation - 911metallurgist

Deposits of comparatively low grade specular hematite amenable to beneficiation by flotation have produced concentrates superior in grade to direct shipping ores. Low grade deposits containing specular hematite (Fe2 O3) as the major iron mineral as low as 25% Fe can be treated with "Sub-A" Flotation to produce concentrates that average better than 62% Fe with less than 9% SiO2 and with a ...
