Gravity separation is used for relatively coarse ore (diameters of approximately 0.1mm to 1.5mm.) 2) Magnetic separation Magnetic separation is a technique for separating iron ore from impurities on the basis of the difference in their magnetic properties. This type of separation is widely used for the beneficiation of magnetite ore.

Beneficiation of Iron Ore - Mineral Processing & Metallurgy

Crushing is done in the conventional manner in 2 or 3 stage systems to approximately all minus ¾ inch which is considered good feed for subsequent wet rod and ball mill grinding. The primary rod mill discharge at about minus 10- mesh is treated over wet magnetic cobbers where, on average magnetic taconite ore, about 1/3 of the total tonnage is rejected as a non-magnetic tailing requiring no further treatment. The magnetic product removed by the cobbers may go direct to the ball mill or alternate
