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

01/05/2020  The iron loss of ultrafine particles in reverse cationic flotation was found to be higher than that in reverse anionic flotation, due to the entrainment of ultrafine hematite particles. Pneumatic flotation cells are currently being considered for use on certain industrial iron ore operations, as promising results that have been observed in some industrial pilot trials in different sites at ...

Flotation of Iron Ore: A Brief Review - MDPI

This is why reverse anionic flotation of iron ore using oleic acid or its soaps is usually performed in a strongly alkaline environment (i.e., above pH 11). Fuerstenau and Cummins [28] concluded that, when oleate was used as collector, the suitable pH value was between 11 and 12 in the flotation of quartz. Table 2. Equilibrium constants for oleate species in aqueous solution [29] (total ionic ...
