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.

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.

When the iron ore is extracted from the mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher’s CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
