Iron processing - Ores, Smelting, Refining: 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 …

This study aimed at the investigation of the effect of colloidal magnetic particles on the magnetic separation of iron ore tailings (IOT). For this, the synthesis and characterization of bare iron, iron-dextran, and iron-oleate magnetic particles is reported. FTIR spectra confirmed that the synthesized particles were composed by magnetite.
