The flotation method most commonly applied is the one that is based on cationic flotation of silica and silicates (reverse flotation), and which is preceded by desliming. As the complexity of mineralogy grows, in terms of extremely fine mineral liberation and very complex intergrowths, a number of signifcant issues come into view.

Flotation response of iron ore depends on its impurities. •. Silica rich ores float better compared to alumina rich ores. •. Clay and gibbsite coat on hematite and hinder flotation. •. SEM studies support less coating of quartz due to coarser size. •. Silica in the form of jasper present in BHJ ore is less floatable.

Reverse flotation of iron ore is now drawing more attention in iron ore industry as an efficient beneficiation process (Ma et al., 2011, Filippov et al., 2010, Araujo et al., 2005, Houot, 1983). In reverse cationic flotation, silica and silicates are floated after depressing the iron oxide by suitable reagents such as starch, dextrin, and CMC.
