The magnetite beneficiation process The degree to which an iron ore is processed depends mainly on the iron ore products being made. The most common iron ores on the market are lump ore, sinter fines and iron ore pellets/pellet feed. Which products are suitable for a mine is dictated by the ore's liberation characteristics and market demands.
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.
