Clariant's reverse flotation featuring Flotigam 2835-2 removes the silica that cannot be removed by magnetic separation. In this process, the ore slurry navigates through a series of large flotation cells, where air is introduced to create the bubbles for float separation. Flotigam 2835-2 collects and floats the silica.

2017-3-19 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 al., 2009; Filippov et
