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

Description and properties of common iron ore minerals. Iron ore minerals are rocks or minerals that contain iron in concentrations high enough to be economically extracted. Common iron ore minerals include: Hematite (Fe2O3): Hematite is the most abundant and important iron ore mineral. It is typically steel-gray to black in color and …
Natural ore, also known as "direct shipping ore," is ore that contains a high percentage of hematite or magnetite (more than 60% iron) and can be fed directly into blast furnaces to produce iron. Iron ore is a raw material used to produce pig iron, which is one of the primary raw materials used to produce steel—steel accounts for 98 per ...
iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand & export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand.
