  • Beneficiation of an iron ore fines by magnetization

    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 abundant iron oxide minerals in soil (Zhang, 2007).However, it cannot be used in iron and steel industry without preliminary beneficiation due to its low grade. Many researchers have investigated the separation of iron minerals from gangue minerals by froth flotation process (Luo et
