pH values in levels usually applied in the reverse flotation of iron ore, i.e. between 8.9 and 11.0. 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 10.5 and the Fe content remained practically stable throughout the range studied.
