·Dry medium intensity magnetic separator DMIMS plays a vital role in enhancing the separation of low grade raw magnetite ore A good understanding of the dynamic separation process of DMIMS would
·In a three drum separator system the first drum is run at medium speed to divide the feed mate rial into low and medium grade products The low grade product is retreated on a low speed drum to produce barren tailings and middlings The medium grade product is cleaned on a high speed drum to produce high grade concentrate and middlings
·Cleaner magnetic separator circuit The cleaner magnetic separator circuit works in the same way as the rougher and regrind magnetic separator circuits using drums and magnets to further separate the magnetite from the non magnetic material The magnetite slurry passes through three cleaner stages and the
For low intensity drum separators used in the iron ore industry the standard field for a separator with ferrite based magnets is T at a distance of 50 mm from the drum surface Work has also shown that such separators have maximum field strengths on the drum surface of less than T The return of a magnetic separator concentrate
