repair methods of several key of the ore flotation cell

Feb 01, 2005· Queiroz (2003) verified that, for certain itabiriteoretypes, the use of attrition allows the increase of the mass recovery to the slimes andflotationconcentrate fractions and the decrease of iron grade in theflotationtailings, 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.
