Iron Ore Beneficiation Flotation Or Magnetic Separation
R.J. Holmes, in Iron Ore, 2015. 9.5.2 Utilization of subeconomic iron ores. As magnetic separators progress toward larger capacity, higher efficiency, and lower operating costs, some subeconomic iron ores have been utilized in recent years. For example, magnetite iron ore containing only about 4 Fe (beach sands or ancient beach sands) to 15.Sep 01, 2020 Dwari et al. (2013) used a combination of dry and wet magnetic separation methods to upgrade a low grade siliceous iron ore with magnetite, hematite, and goethite as major iron minerals. The study showed that for particles finer than 200 m, the separation methods produced a magnetic concentrate with 67 iron and iron recovery of 90 .
