  • 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

    Metallurgy and Ore Beneficiation Unlike the more typical magnetite deposits where the mineralisation is finely disseminated in siliceous bedding planes and commonly referred to as taconite deposits, the magnetite at Buena Vista is an intrusion into a volcanic andesite and as such is coarser in association with the siliceous host rock.

  • Magnetite Iron Ore Benefication

    16/9/2020 Iron ore mining often focuses on looking for hematite deposits known as red iron ore, and magnetite, as they have naturally weak magnetic fields that aid in their purification. Hematite, however, responds better to the flotation process in iron ore beneficiation than magnetite, so it is the preferred type of ore.
