A New Approach to Processing Rutile from Ilmenite

2018-7-26  This result suggests a new process flow of rutile extraction from ilmenite ore: natural ilmenite ore can be first oxidized in air below 929 K to coprecipitate rutile, and hematite, and then hematite will be reduced to a metallic form by a reducing gas at a low temperature, which will be followed by a simple acid leaching to dissolve the metallic iron.

Ilmenite/Rutile Alpha Thermal Process

Ilmenite is often beneficiated to produce synthetic rutile or titaniferous slag [Boateng, 2016]. Although numerous technologies are used to produce synthetic rutile, nearly all are based on either selective leaching or thermal reduction of iron and other impurities in ilmenite.

Towards sustainable TiO2 production: An

2018-9-20  Ilmenite is a titanium-oxide mineral which is upgraded to 85 to 95 percent titanium oxide which in turn comes as rutile. Synthetic rutile production consists of two stages including pyro-metallurgical processing, while ilmenite is heated in a large rotary kiln. It produces iron oxide impurities within the crystal lattice.

A review of mineral processing of ilmenite by flotation

2020-10-1  As a combined processing technology, rare earth drum magnets are first used to remove ilmenite from mined heavy mineral concentrate feed, from which most of the ilmenite can be recovered. Then non-magnetic minerals are processed by electrostatic separation to obtain conductor minerals (rutile and leucoxene) and non-conductors (consisting of zircon, kyanite, quartz, monazite and staurolite).

Feasibility study of the new rutile extraction process

It is found that rutile can be produced from common natural ilmenite ores not only by the reduction as the conventional titanium-rich slag process but also by an oxidation. Then, the oxidation experiment was conducted in air using Australian ilmenite ore to obtain rutile as one of the coexistent phases.
