· An iron ore with 57% Fe was found to be unresponsive to conventional beneficiation techniques because of the inherent complex mineralogy pertaining to finegrained silica particles that are locked within hematite grains. A different approach based on reduction roasting and microwave heating followed by magnetic separation was considered to reduce and recover the iron values. The effects of ...
Beneficiation of −2 mm lowgrade iron ore tailings (50·7%Fe, 10·8%SiO 2 and 4·4%Al 2 O 3) from Western Australia was studied. The sample consisted of hydrohaematite, goethite and quartz, with lesser kaolinite and shale. Two processing options were tested, which were wet highintensity magnetic separation (WHIMS), either using deslimed or untreated feed, and reduction (magnetising ...

In the dry beneficiation process, iron ore is ground to 02 mm size. After screening, the fines are passed through a very high gauss rare earth magnetic separator (up to 8,000 gauss). A demo plant has been set up experiments on many types of raw materials were carried out in the last 5 years, which have proven that upgradation of Fe from 5052% to 5660% Fe is possible. The nonmag contains ...
