10-03-2016  Iron ores can be concentrated either by direct anionic flotation of iron oxides or reverse cationic flotation of silica. In direct flotation, oleic acid or its sodium salt is the preferred reagent. Several studies on oleate-hematite interactions suggest that the oleate adsorption on hematite mainly depends on solution pH ( Paterson and Salman, 1970 , Peck et al., 1966 , Pope and Sutton, 1973 ).
