If either ore or the gangue (one of these two) is attracted by a magnet then ore can be separated from the impurities with the help of magnetic separation method. For example: 1) The magnetic impurities such as iron and manganese tungstates (FeWO 4 ,MnWO 4 ) present in tin stone (SnO 2 , non-magnetic) are separated by this method.

Chemical Separation: One way of concentrating the ore is by chemical separation. For example, the separation of aluminium (Al) from the bauxite ore. This process of separating aluminium from the bauxite ore is also termed Bayer’s Process. Hot NaOH reacts with the bauxite ore which leads to the formation of sodium aluminate which is water-soluble.

The extraction of iron from its ore is the third and the penultimate process in metallurgy, which is the process of separating metals from their ores. The common ores of iron are iron oxides. These oxides can be reduced to iron by heating them with carbon in the form of coke. Heating coal in the absence of air produces coke.

AG mills crush the ore without the need for iron or steel grinding media. They are used when the ore is hard enough for the tumbling ore to grind itself. In SAG milling, ∼0.15 m 3 of 13 cm diameter iron or steel balls are added into the mill per 0.85 m 3 of ore (i.e., 15 vol.% “steel”) to assist grinding. SAG mills are much more common.
