An 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.
Structure and properties
Ilmenite, also known as manaccanite, is a titaniumiron oxide mineral with the idealized formula FeTiO 3. It is a weakly magnetic black or steelgray solid. From a commercial perspective, ilmenite is the most important ore of titanium. Ilmenite is the main source of titanium dioxide, which is used in paints, printing inks , fabrics, plastics, paper, sunscreen, food and cosmetics.
Ilmenite an overview ScienceDirect Topics
In the present processing flowsheet, the ore is first processed with wet lowintensity drum magnetic separator to concentrate strongly magnetic vanadic titanomagnetite, with its tailings classified into coarse and fine fractions; and then the ilmenite is respectively recovered from the two fractions, by highgradient magnetic separationreverse flotation flowsheet.

Ilmenite Rutile Separate Soby
Rutile may be separated from ilmenite or ilmenite ores by agitating a mixture of ilmenite and rutile in particle form in an aqueous solution containing a collection agent to which hydrogen peroxide has been added. The slurry in agitated form is treated with air to produce a froth.
Triboelectric properties of ilmenite and quartz minerals
Triboelectric separation of ilmenite ore According to the optimal results of triboelectric separation on the mixture of ilmenite and quartz, the separation experiment of ilmenite ore was conducted at the parameters of 40m 3 /h airflow rate, 6g/s feed rate, and 20kV voltage.
A Novel Process for Titanium Sand by Magnetic Separation
May 07, 20150183;32;A typically lowgrade titanium sand was first ground and then processed by lowintensity magnetic separation (LMS) and high gradient magnetic separation (HGMS) to recover titanomagnetite and ilmenite, respectively; as the TiO 2 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.

A discussion of magnetic separation techniques for concentrating ilmenite and chromite ores
Mineral processing can involve four general types of unit operation comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considere
