Ironprocessing -Iron processing - Ores:Ironores 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 distributediron-bearing minerals are oxides, andironores consist mainly of hematite (Fe2O3), which is
