Reagents in iron ores flotation ScienceDirect

Feb 01, 2005· Queiroz (2003) verified that, for certain itabirite ore types, the use of attrition allows the increase of the mass recovery to the slimes and flotation concentrate fractions and the decrease of iron grade in the flotation tailings, iron grade in the slimes and SiO 2, Al 2 O 3 and P grades in the concentrate, resulting in higher figures for Gaudin’s selectivity index.
