Magnetite is an essential iron-bearing mineral. The primary method of magnetite ore beneficiation involves successive steps of crushing, grinding, and magnetic separation. Reverse cationic flotation is used at the final stage to remove silicate and aluminosilicate impurities from the magnetite concentrate and reduce silica content to Although magnetite contains the highest iron content (72.4%) compared with hematite and goethite, the majority of the magnetite deposits, especially those located in Australia, contain low iron (~14% to ~45% Fe) and are of low economic value in its low-grade ore state. Invariably, low-grade magnetite ores processing warrants furtherAssessing the performance of a novel pneumatic magnetic separator for
