Abstract: The industrial application of cyclonic static micro-bubble flotation column in the cationic reverse flotation of magnetite ore is its first successful case for the reverse flotation of iron ore. To better use this new type equipment, the middling issue in its industrial application is pointed out and a middling treatment mode different from conventional flotation process is proposed ...
01-01-2001· The advantage of the reverse circuit over the direct flotation is an increase in the plant capacity caused by the much lower proportion of material floated. CURRENT PROCESS The ore is crushed, homogenised, sent to the stock pile close to the plant and then fed to a crushing circuit to be reduced to -7.94 mm (5/16"').

Reverse anionic flotation of magnetite is conducted at a higher pH value (pH 11–12) than reverse cationic flotation (pH 10–10.5). Since the point of zero charge (PZC) of pure magnetite is around pH 6.5, the surface charge of magnetite in reverse cationic flotation (pH 10–10.5) would be less negatively charged than that at pH 11-12 (Li et ...

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 ).
