Flotation of Iron Ore: A Brief Review

Jul 30, 2020  The primary gangue mineral in iron ores is quartz. In addition to quartz, iron-bearing silicates (e.g., amphiboles and pyroxenes), carbonates, clays (e.g., kaolinite), and gibbsite are also commonly present in iron ores [1,2]. Iron ore beneficiation aims to eliminate the harmful elements in iron ore concentrate, which could impose a ...
