A classification of reagents for iron ore flotation and their adsorption mechanism have been summarized. ... (HTAB) was used as collector for both alumina and silica removal [90]. Higher doses of CTAB enable more adsorption of the collector on to the gangue surface resulting in removal of the slimy and alumina-enriched fraction as …

In conventional operations of iron ore beneficiation by flotation, the flotation feed is deslimed to remove the 10 µm fraction prior to flotation (Filippov et al 2014), thus the unselective flocculation effect of starch does not affect the flotation selectivity. Contrary to what occurred in this study, where the pure mineral samples used …

A bulk of silica sand was taken from Kowli-Kosh silica sand mine to reduce its hematite content by reverse flotation. The raw sample consisted of 97.38% SiO 2 and 0.213% Fe 2 O 3 and traces of Al 2 O 3, CaO, MgO, Na 2 O, K 2 O, TiO 2. Fig. 1 illustrates a general block diagram for the hematite removal process from silica sand.
