DetailsIntroduction. Quartz is the major gangue mineral present in iron ores. Flotation is the usual concentration method employed for the ores in the fine size range (<149. μm).. Different flotation routes are available: (i) reverse cationic flotation of quartz; (ii) direct anionic flotation of iron oxides; (iii) reverse anionic flotation of activated quartz.
DetailsIntroduction. Iron is one of the most common elements in Earth's crust. The primary industrial types of iron-bearing minerals include oxides and hydroxides and, to a lesser extent, carbonates: magnetite [Fe 3 O 4], hematite [Fe 2 O 3], goethite [FeO(OH)], limonite [FeO(OH) × nH 2 O] and siderite [FeCO 3].The genesis of iron ore deposits is …
Details1. Introduction. Iron ore resources are extremely rich in China, but most of them belong to complex ultrafine iron ore with high content of impurities [].Reverse flotation has been proved to be an efficient process for economic reasons [2 – 6].In order to ensure iron concentrate grade and iron recovery, a large number of processing …
DetailsKaolinite is a common gangue mineral in iron ore and sodium silicate has been used widely as a dispersant of silicate gangue minerals including kaolinite in various iron-ore flotation methods over a wide range of pH. Its actual dispersive effect on kaolinite under iron-ore flotation conditions has received very limited attention, however.
