· This material is then further refined through iron ore beneficiation by using a dehydration tank to remove water content and by applying highintensity magnetic fields generated by a disc magnetic separator. At this stage, lowgrade ore that still contains metal value is placed back at the start of the cycle, and tailings, which are even lowergrade residues, are removed as waste.

Iron Ore Beneficiation Magnetic Separation Quality Planning. Ores can often respond to gravity andor magnetic separation. However due to the presence of loweriron content iron minerals such as goethite mass yields and recoveries to high grade concentrates can be low. Tradeoffs are then required between recovery and product quality iron grade and penalty element content . Send Email ...

The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores. There are, however, other impurities in some deposits that ...
