Advantages of ilmenite separation process

us5595347aclaims (31) 1. a process for the separation of ilmenite from raw sand or mineral concentrates thereof, 2. the process according to claim 1, further comprising the step of: 3. the process according to claim 2, further comprising the steps: 4. the process according to claim 3, wherein said ilmeniteilmenite can be converted into pigment grade titanium dioxide via either the sulfate process or the chloride process. ilmenite can also be improved and purified to rutile using the becher process . ilmenite ores can also be converted to liquid iron and a titanium rich slag using a smelting process. pilot-scale demonstration of ilmenite processing technologyilmenite locked in gangue particles in the gravity separators and some ilmenite losses to the magnetite/titanomagnetite stream. overall ilmenite recovery to the ilmenite concentrate stream was estimated at 64%. the ctl process contains five major process steps: atmospheric chloride leaching, oxidation, titanium dioxide (tio2) production and manufacturing process tio2 is produced from either ilmenite, rutile or titanium slag. titanium pigment is extracted by using either sulphuric acid (sulphate process) or chlorine (chloride route). the sulphate process employs simpler technology than the chloride route and can use lower grade, cheaper ores. however, it

ilmenite separation process application

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.
