Mineralogical characterization of the typical coarse iron ...

2019-1-15  The appropriate dense media for the dry separation of coarse iron ore were determined by investigating the particle size distribution, and the bulk density of dense media powders. Based on the compositions of the binary dense media, a regulatory model of the bed density was established and was proven efficient for predicting the variation and ...

2017-9-1  A dry density-based fluidized bed separator was used to beneficiate coarse particulate iron ore. The atomized iron powder and zircon sand, with specific size fractions of 150–75 and 250–150 μm, were mixed in certain proportion to form a binary dense media.The results indicated that the binary dense media efficiently formed stable fluidization within the fluidized bed for subsequent ...
