itabirite mineralisation is a metamorphosed iron formation composed of iron oxides (hematite, magnetite, martite), abundant quartz, very rarely mica and other accessory minerals. brazil’s itabirite deposits range in scale from 1 to 4 billion tonnes, with average grades of between 37% fe and 52% fe.
among them, magnetite-hematite is a common mixed ore, and its beneficiation usually adopts a combined process flow composed of multiple beneficiation methods. single magnetite-hematite the single magnet-hematite is mostly fine-grained; the gangue mineral is mainly quartz, and some of it contains iron silicate. get price
