Dry separation of particulate iron ore using density …
A gas–solid fluidized bed has been used to separate particulate iron ore (+250–500 μm in size) by segregating the particles by density.The ore particles were put into a cylindrical column of inner diameter of 100 mm and bed height of 50 mm, and were fluidized at a given air velocity u 0 /u mf = 1.2–3.2 for 10 min. u 0 and u mf are the …
