Iron ore concentration process with grinding circuit, dry

Currently the process is carried out dry and partially wet. Dry processing normally goes from the mining (extraction of the ore in the mine) up to the sieving and crushing operations. When processing natural fines from ores, the wet stage is started after crushing with the addition of large quantities of water. The wet stage begins at grinding.

Mining - Concentrator ArcelorMittal

For iron ore this involves crushing the ore and then concentrating it in different ways, for example by milling, flotation or magnetic separation. At some sites the ore is processed further and pelletised for use in direct reduced iron (DRI) steelmaking. In the processing stage, the mined material is transformed into usable raw material.
