mining technology: beneficiation of IRON ORE

The rate of reduction of both iron ore and quartz varies (Figures 1 to 3). Quartz dissipates easily, breaking down to fines with little applied stress. Though the hardness value of quartz (i.e. 7 on the Mohr''s scale) is a bit higher than the iron ore (Hematite (5.56.5), Magnetite (5.56), it is far more brittle than iron ore (Gribble, 1988).
