Primary crushing brings run-of-mine ore down to a maximum size of the order 4″ to 6″ in average diameter; secondary crushing receives feed at −6″ and reduces it to below "Dry" crushing includes work on ore as mined, which may be somewhat moist when delivered. It is succeeded by comminution in water, arbitrarily called "grinding".

Gravity Separation: Since iron is heavier than many impurities, it can be separated by washing the ore. The lighter impurities are carried away, leaving the heavier iron-rich particles behind. Magnetic Separation: For ores like magnetite that are naturally magnetic, magnets are used to separate the iron-rich material from the non-magnetic impurities. By the end of this step, the …

Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion. Details
