Ores Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments Most are sedimentary, but many have been changedAt the carbon contents typical of steels, iron carbide (Fe 3 C), also known as cementite, is formed; this leads to the formation of pearlite, which in a microscope can be seen to consist of alternate laths of alphaferrite andIron processing | Definition, History, Steps, Uses, & Facts
