Magnetic separation is the most efficient separation method of these technologies. Modern magnetic separators are capable of processing up to 500 t ore/h per unit at a very low operating cost . Flotation has the advantage of good selectivity, but it often has much higher operating costs than magnetic separation.
This mill pulverized the large chunks of ore that came directly from the mine. Edison planned to process 1200 tons of iron ore every twenty hours. The plant had three magnetic separators that could produce a total of 530 tons of refined ore. There was other equipment to re refine what was left over to extract even more ore.

ADVANCES IN MAGNETIC SEPARATION OF ORES Magnetic separation of iron ores is one of the fastest growing segments of the minerah beneficiation industry. The tonnage of taconite ores processed annually by magnetic separation toill, in a few years, reach 100 million. by L. A. ROE M agnetic separation occupies an attractive posi
Magnetic Separation and Iron Ore Beneficiation. Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.
IRON ORE MEDIUM INTENSITY Medium Intensity Magnet Separator are drum magnets on which are mounted axial rows of permanent magnet blocks generating a very high and homogenous magnetic gradient to attract and concentrate the weakly magnetic Ferrous ore.
The magnetic roasted iron is delivered to a tube mill and reduced to 2 mm., and from thence is elevated by a centrifugal pump to settling tanks from which it is tapped to the cleaning separators, two in number, of the same type as the machines working on raw ore. The final results of the magnetic separation are a concentrate carrying 50.81 per cent. zinc and tailing averaging 3.98 per cent. zinc; the feed averages 30.81 per cent. and the extraction in terms of total zinc in the feed is 98 ...
Eriez Permanent Magnetic Separators require no electric power. With proper care, they can last a lifetime with very little loss of magnetic field strength. Eriez permanent magnets are supplied for a wide range of applications including dry bulk materials, liquids or slurries and even high temperature applications.
