Dense Medium Separation (DMS)
The paper discusses various aspects of the application of heavy-medium separation to the processing of hematite ore at Sishen and Thabazimbi. The two main factors to be borne in mind in the design of a plant for such beneficiation are the Iow unit value of the iron ore produced and the high separation densities required.

A review on the characterisation and processing of oolitic iron ores
These deposits currently constitute a significant portion of Australia's iron ore exports. The CID ores typically contain 54–58% Fe and represent ∼25% of the total 455 Mt of iron ore mined from the Hamersley Province in 2011–2012 and this tonnage is increasing annually (Kneeshaw and Morris, 2014). 2.
