The iron-making process requires high-quality raw materials, with Fe ≥ 64% and <2% alumina and silica each, to enhance blast furnace productivity at a given energy consumption rate.
Hence, to meet the growing steel demand, the demand for iron ore is also increasing. While, on one side reserves of good quality iron ore are depleting, on the other side the steel companies require better quality of iron ore with lower gangue content due to the addition of higher capacity blast furnaces for higher productivity, lower hot metal cost, and …

Multotec Screens reduce pegging and blinding: Blinding occurs when any particles such as: dirt, minerals and other substances, stick to and bridge across your screening surface apertures. This creates a stubborn paste that blocks screening material from movement through. Pegging is the occurrence of irregular material blocked in the screen apertures, which happens when stones …
Magnetic separator separates the iron ore feed material into two or more components. If the purpose is to produce a magnetic concentrated iron ore then the other component which is non-magnetic is the tailings. In some cases there can also be a possibility of separating the less magnetic third component which is called middlings.
If you think the differences between dry and wet screen mining are limited to the presence or lack of water, then you're missing several important points. First of all, wet separation technology requires additional equipment, including the spray nozzles that funnel the water. Extra plant capital is on the agenda when these additional stages enter
