19-03-2021 · As Tripathy explains, some types of FDMS can’t separate ores smaller than 45µ – frustrating given iron ore particles can be as small as 30µ. Then there are more fundamental problems of magnetic separation. Materials like iron are perfect for FDMS, after all, but what about non-magnetic metals like aluminium, copper or zinc? An attractive ...

White Paper

best grades of iron ore are actually sourced from lower-grade in situ ore bodies. In other words, sometimes the purest iron ore can be made from relatively low-grade ore bodies that then use processing to separate the higher-grade iron ore and generate higher-grade products. So, can the existing producers shift direction to

Iron ore - Wikipedia

Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the
