Quantification of the mechanisms governing the packing of iron ore fines
For wet particles, ρ A varies with moisture content, as given in Fig. 7 for the iron ore fines considered. The effect of the bulk density of agglomerates on overall bulk density can be quantified as the difference between the bulk densities for the wet and dry cases Δρ b assuming ε inter is constant, given by (5) Δ ρ b = (1 − ε inter ...

Using Iron Ore Ultra-Fines for Hydrogen-Based Fluidized …
For boundary A/B, a void fraction of 0.383 at minimum fluidization velocity was taken, which was too low for iron ore ultra-fines, given the loose bulk density between 1800 and 2200 kg/m 3. A true density in the range of 4800 to 5100 kg/m 3 resulted in a void fraction of 0.5 to 0.65, meaning that the A/B boundary was reduced from Ar = 88.5 to ...

In this case, the high-density iron ore particles sank to the bed bottom as the iron concentrate, thereby improving the concentrate grade. However, when the gas velocity exceeded the limit, the bed became unstable because of the bubbling turbulence, which affected the density-based separation of coarse iron ore particles.
