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.It was called the barren waste this land that is now Michigan’s Upper Peninsula However since its first iron ore shipment of two hundred pounds in 1846 the Upper Peninsula mines (below) have produced well over one billion tons of iron ore Some barren waste! Iron ore is Michigan’s most valuable non fuel mined commodity.
