magnetization process for extracting iron ore

Nov 10, 2017· 1. Introduction. Hematite (α-Fe 2 O 3) is widely distributed in various rocks and is one of the most common and abundantironoxide minerals in soil (Zhang, 2007).However, it cannot be used inironand steel industry without preliminary beneficiation due to its low grade. Many researchers have investigated the separation ofironminerals from gangue minerals by froth flotationprocess(Luo et ...

    Common Iron Ore Extraction Processes Mining pedia

    Froth flotationprocess is mainly adopted to the extraction of weak magnetic iron ore with fine particles, including positive flotation and reverse flotation process. Among them, the positive flotation process is suitable for the quartz hematite without easily floating gangue, while the reverse flotation process is suitable for the extraction of iron ore with easy-to-float gangue ore.
