Crushing And Screening Iron Ore Concentrate
Mineral Processing
This process includes ore crushing, screening, ore grinding, classification, and magnetizing roasting of weakly magnetic iron ore. If necessary, desliming and washing will be done in advance, in order to ensure the ore (crude ore) from an open-pit mine or underground mine can be delivered to the mineral processing plant.
