the efficient use of ore enables us to deliver exceptional coal washing consulting services to various industry sectors. martin and robson's dms magnetite ore has a very high magnetic content. we employ an advanced process of mechanical and chemical separation which uses magnetic separators in the final process.
the dominant areas where the drum magnetic separators are used are the processing of magnetite titano-magnetite and vanadic titano-magnetite ores. figure 3 shows the wet drum magnetic separator and its operation for vanadic titano-magnetite. the technical specifications of applied wet drum magnetic separators are illustrated in table 2.
at present most u.s. iron materials are produced from magnetic taconites which are ground to a nominal minus 270 mesh (53 micrometers) beneficiated by wet low-intensity magnetic separation and pelletized. the taconite ore bodies generally contain 19 to 25 percent magnetic iron defined as iron occurring in the mineral magnetite.
dense media separation (dms) - medium grade; and; iron ore (coarse grade) manufacture current magnetite production is a by-product of the copper operations and as such is recovered from the concentrator floatation tails stream by magnetic separation. approximately 15% by weight of magnetite is removed by 'cleaning' and 're-cleaning' of the
the problem of practically separating iron-ores as found in the mines is very different from the separation of a purely magnetic substance from a purely non-magnetic one since the crystals of magnetite scattered through the ore-bearing rock and sometimes collected in masses are of very different sizes.
