beneficiation for high grade haematite and magnetite

Sundance Resources Limited

Hematite is a black, grey or reddish-coloured mineral which is mined as the main source of iron. Hematite has traditionally formed the bulk of global iron ore production, and high-grade hematite is often referred to as "Direct Shipping Ore" or "DSO" because it is mined and beneficiated using a relatively simple crushing and screening ...
