Consoli et al. classified iron ore tailings from the Iron Quadrangle as predominantly silty sand, with a specific gravity of solids of 2.92. Similarly, Mmbando, Fourie and Reid [ 44 ] concurred, characterizing most of the Iron Quadrangle iron ore tailings as primarily silt or sand, and their specific gravity was 3.71.
4.2 Fineness modulus, Specific gravity, Bulk density The specific gravity and the percentage of voids are important parameters for fine aggregate in designing the mix proportions of concrete. In masonry mortars, the bulk density of fine aggregate in loose state was used in converting volume mix proportions to weight ratios.
Mineral and rock densities are normally expressed as specific gravity, which is the density of the rock relative to the density of water. ... And if you know your igneous petrology, you will see that the more mafic (rich in magnesium and iron) a rock is, the greater its density.

Three tests were performed to define the specific gravity of the iron ore tailing samples: one test at LMS-UFV and two at LabGeo-FEUP to verify the similarity of the samples sent to both laboratories. The tests followed the ABNT NBR 6458:2016 and ISO 17892–3:2015 methods, respectively.
The flotation has been successfully applied to process the iron ore for the particle size (Ps) from 10 µm up to 150 µm. The presence of the slimes (Ps < 10 µm) is harmful on the reverse flotation of quartz, so they are usually prior removed by hydrocyclones. The main effects of the presence of slimes on the flotation are related to the increase on reagents consumption, …
