Iron ore mining process and the necessary equipment

Iron ore crushing and screening

Mining and processing of iron ore involves coarse crushing and screening. Iron ore is beneficiated by crushing and then separating the iron from the gangue minerals through screening. This is usually so efficient that lower grade ore can be treated especially when the magnetite is quite coarse. Common iron ore crushers are jaw crusher, cone crusher and fine jaw crusher.

Dry magnetic separation and wet magnetic separation

You will obtain three kind of iron ore particles after screening, respectively of 75~12mm, 12~2mm, 2~0mm in size. The largest ore particles pass to dry magnetic separation with shaking chute, the middle ones are moved to dry magnetic separator with coarse jigging, and the smallest to wet magnetic separator with fine jigging. The middlings produced by three processes are moved to screening process. The tailings of wet magnetic separation will be discharged directly.

Grinding and fine crushing

After the second crushing, iron ore particles are moved to secondary crushing and the first ball mill grinding. With fine ore particles, it is more efficient to upgrade iron ore. Wet ball mill and fine ore crushers are used during this process.

Spiral classification

Tow stage spiral classification of close-circuit is conducted, with second ball mill grinding after the second classification.

Flotation desulfurization

The obtained iron ore materials are moved to flotation desulfurization process, then to weak magnetic separation. The obtained product is iron ore concentrate. And low iron content material is discharged as tailings. You will also obtain sulphide concentrate as by-product through flotation desulfurization.
