    Mining and Beneficiation Waste Production and Utilization

    Mineral beneficiation is the first step after mining in the minerals and metal value chain. Mineral beneficiation consists of the manipulation of the physical properties of the ore to (1) produce desired particle sizes for a final product (2) liberate and concentrate the value mineral from the gangue material.

    Beneficiation Processing of Iron ore

    The main iron mineral in magnetite ore is the ferrous iron oxide magnetite (Fe3O4). Magnetite ore requires complex processing to separate magnetite minerals from other minerals in the ore to produce an almost pure magnetite concentrate with an iron content of between 68% Fe and 70% Fe that is highly sought after by steel makers.
