mineral separation iluka virtual mine site tourmineral separation. it is primarily used in the production of ceramic tiles. other applications include use in refractories and foundry casting and a growing array of specialty applications as zirconia and zirconium chemicals. titanium dioxide (mined as ilmenite or rutile) is a dark coloured mineral which, with processing, becomes white and opaque. titanium ore processing and beneficiationan ore of magnetite and ilmenite may, however, employ wet magnetic separation to remove magnetite, and all flotation for recovery of the ilmenite in a high grade product. in this case all the gravity circuit including the jigs and tables can be eliminated.

a discussion of magnetic separation techniques for magnetic separation technology selection and flowsheet configuration. case study 1: dry magnetic separation of ilmenite before electrostatic separation the deposit for case study 1 was a typical aeolian reworked mineral sand deposit with a heavy mineral assemblage of ilmenite, rutile, zircon, sillimanite, monazite, magnetite and other minor minerals. us3935094athe ilmenite concentrate is then subjected to a magnetic separation in a wet separation process and the high magnetically susceptible chromite contaminant is removed therefrom. the assay of the magnetics which are separated from the primary concentrate consists of chromite and cr 2 o 3 bearing mineral of about 20 percent of the chromite present in the primary concentrate. becher processthe becher process is an industrial process used to upgrade ilmenite to synthetic rutile. the mineral, ilmenite, contains 55-65% titanium as tio2, the rest being iron oxide. the becher process removes the iron oxide, leaving a residue of synthetic rutile, which is more than 90% tio2. a novel process for titanium sand by magnetic separation and a typically low-grade titanium sand was first ground and then processed by low-intensity magnetic separation (lms) and high gradient magnetic separation (hgms) to recover titanomagnetite and ilmenite, respectively; as the tio2 grade of the sand is low, the primary treatment of the sand by magnetic separations is effective, with 78.45% by mass weight of the sand discarded as tailings.
