Iron ore
Banded iron formations are known as taconite within North America The mining involves moving tremendous amounts of ore and waste The waste comes in two forms: nonore bedrock in the mine ( overburden or Analysis of the current technical solutions for the processing of iron ores showed that the highgrade ores are directly exposed to metallurgical processing; by comparison, lowgrade ores, depending on the mineralogical and material composition, are directed to beneficiation including gravitational, magnetic, and flotation processes or their Mineral and Technological Features of Magnetite–Hematite Ores
Iron processing Ores Britannica
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 ironbearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is red; There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone These ores vary in colour from dark grey, bright yellow, or Iron ore BHP
