Reagents types in flotation of iron oxide minerals: A
Jun 10, 2010· In this paper, several studies describing the processing of iron ores via direct and reverse cationic and anionic flotation are reviewed The objective of this review was to present and identify the effects of different flotation conditions on removal of specific impurities in iron ore such as quartz, alumina, phosphorous, and sulfurThis article discusses the effect of physical and chemical modifications of starches on the anionic and cationic flotation of silica from oxidized iron ores and magnetitetaconite concentrates, and the results of the interaction of starch, pH, and calcium ions on the flocculation, clarification, and filtration of iron ore slimes and magnetitetaconite tailingsThe Use Of Starches And Starch Derivatives onemine
