2/1/ 32 A significant advantage of reverse anionic flotation circuits is the omission of de sliming prior to flotation 52 attributed the higher tolerance to slimes using reverse anionic flotation to the increased surface charges on the oxides at higher pH pH 11 12 pH values in levels usually applied in the reverse flotation of iron ore ie between 89 and 110 The results presented in Figure 6 show that the rise in pH led to a significant rise in the recovery of Fe in the concentrate The content of SiO 2 diminished for pH values up to 105 and the Fe content remained practically stable throughout the range studied
