Iron ore dressing process_Metal Ore Crushing for Dressing

Iron ore dressing process

Iron ore is an important raw material for iron and steel production. Iron is extracted from natural iron ore through crushing, grinding, magnetic separation, flotation, gravity separation, etc.The iron ore put into the furnace should have a suitable particle size and sufficient strength. It is generally required that the ore particle size should be in the range of 5-40mm. And after processing, the iron ore tailings can be used as construction aggregate for concrete, unburned bricks, and other industries.

Multiple models for selection, can be customized according to customer requirements.

Working Process

The iron ore processing and production process mainly includes three processes: crushing, grinding and beneficiation.
Crushing and screening
Large pieces of iron ore are uniformly sent to jaw crusher or coarse crushing mobile station for coarse crushing by vibrating feeder through silo; After the coarse crushed iron ore is screened by vibrating screen, it is sent to the single cylinder hydraulic cone crusher by belt conveyor for intermediate crushing; The iron ore materials after intermediate crushing are sent to the multi cylinder hydraulic cone crusher for fine crushing;
Milling
The 0-12 mm iron powder screened by the vibrating screen is evenly sent to the pulverizer for grinding, and screened by the spiral classifier. The unqualified iron powder is sent to the pulverizer for further grinding;
magnetic separation
The iron powder meeting the requirements of mineral processing is sent to the magnetic separator for high-intensity magnetic separation and magnetic separation to remove impurities;
drying
The iron concentrate can be obtained by feeding the obtained iron powder into the dryer for drying.
