In fact, most of the Earth''s major iron ore deposits are found in rocks that were formed more than 1.8 billion years ago. Iron ore has turned into the world''s most essential raw material that produces iron, which is then used to make steel. Various industrial processes involving modern technology are utilised to process iron ore into steel.

Low grade Iron Ore Beneficiation and the . The reasons for choosing jigging for the iron ore beneficiation over other processes include (i) relatively easy separation, (ii) beneficial trade-off between operating cost and reduced yield relative to dense medium processes, (iii) ability to treat ores requiring cut densities higher than a density of 4.0, and (iv) physical characteristics of the ...

Iron ore •Some iron ore only requires crushing and no processing. This is referred to as "direct shipping ore" (DSO). •Most South African iron ore does require processing which involves DMS or gravity concentration, usually jigging. •Arcelor Mittal South Africa uses lump (-25 +8 mm) iron ore in their blast furnaces and fine iron ore (-8

How iron is made

Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94% iron and 3-5% carbon with smaller amounts of other elements.
