Development of an alternative to magnetite for use as heavy media …
•Another important factor which largely dictates the consumption of dense media are the losses to clean-coal and rejects. The typical losses for both MFFD and magnetite are shown in Fig. 6. The MFFD losses per tonne of clean-coal varied from 0.64 to 0.96 kg, whereas, the magnetite losses varied from 0.8 to 1 kg.
