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),

When ore is crushed and split into lump and fines components, there are systematic differences between the lump and fines compositions. The lump component is usually (but not always) richer in iron, and with less silica and alumina, than the fines product.
