iron concentration iron ore in crushing circuit
Concentration is the second step in taconite ore processing As the iron ore minerals are liberated by the crushing steps the iron bearing particles must be concentrated Because only about 33 percent of the crude taconite becomes a shippable product for iron making a large amount of gangue is generated.
