Effect of mineral geology, mineral size and settling time

Jul 25, 2011 The efficiency of selective dispersion process strongly depends on mineral geology and particle size. Under a particular settling condition, a high grade concentrate containing 67.9 wt.% Fe, 1.2 wt.% Al 2 O 3 and 1.25% wt% SiO 2 with 58% iron recovery is achievable using off grade iron ultra fines containing 57.8 wt.% Fe, 7.55 wt.% Al 2 O 3 and 7.15 wt.% SiO 2.

Iron processing Ores Britannica

Iron processing Iron processing Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is
