Iron Ore Flotation RoutesReverse flotation separation of hematite from quartz,,01-08-2019· 1. Introduction. With the over-depletion of high-grade iron (Fe) ore deposits, froth flotation has become the most important mineral separation technique in processing of medium-grade and low-grade iron ores (Rocha et al., 2010, Quast, 2017, de Medeiros and Baltar, 2018, Kumar et al., 2018).Medium-grade and low-grade iron ores are commonly complexCHAPTER-9 FROTH FLOTATION AND ITS APPLICATION TO,,Frothers Frothers, as defined by flotation operators, are compounds used specifically for creating a flotation froth. However, most collectors used in iron ore processing produce adequate froths. The general types of these frothing collectors include long- chain carboxylates, sulfonates or sulfates, and amines as listed in Table 9.1.
