Ilmenite

Ilmenite. Definition. Ilmenite is a lustrous black to brownish rhombohedral mineral that is an ore of titanium. Ilmenite occurs in igneous rocks and is one of the principal dark minerals observed in beach sands. It is a weakly magnetic black or steel-gray solid. From the commercial perspective, ilmenite is the most important ore of titanium. Get price

Ilmenite Activation during Consecutive Redox Cycles in

Jan 07, 2010Ilmenite, a natural mineral composed of FeTiO3, is a low-cost and promising oxygen carrier (OC) for solid fuels combustion in a chemical-looping combustion (CLC) system. The aim of this study is to analyze the behavior of ilmenite as an OC in CLC and the changes in its properties through redox cycles. Experiments consisting of reduction−oxidation cycles in a thermogravimetric analyzer Get price

Illmenite Ore Processing

ILMENITE (Iron Titanium Oxide) - galleries. Ilmenite by itself is not a profitable iron ore as the titanium inhibits the smelting process. Ilmenite, hematite and corundum all have similar structures and belong to a more or less informal group called the Hematite Group with a general formula of A 2 O 3. Get price

A review of mineral processing of ilmenite by flotation

It is found that microwave irradiation can increase the crystalline compound of ilmenite and promote the cracking separation of ilmenite particles and associated gangue minerals due to the selective heating characteristics by this pre-treatment method (the heating speed of ilmenite is faster than associated gangue minerals and thus thermal stresses are caused) (Zhao et al., 2014).

Benzyl Arsonic Acid

A new flotation collector, benzyl arsonic acid, was used for the flotation of ilmenite. ESCA, Auger spectroscopy, and chemical analysis were used to investigate the correlation between the variation in surface constituents and the flotation recovery of ilmenite. The surface study of ilmenite and a study of the effect of surface modifications on the flotability of ilmenite are also presented Get price

WEI LI CARBOTHERMIC REDUCTION KINETICS OF ILMENITE

For microwave processing of ilmenite, Itoh et al. described the microwave oxidation of rutile extraction process, in which rutile is extracted from a natural ilmenite ore by oxidation and magnetic separation followed by leaching with diluted acid [32]. Kelly and Rowson investigated microwave reduction of oxidized ilimenite concentrate [33]. Get price

EXISTING BENEFICIATION PROCESS FOR ILMENITE ORE

The microstructure of this particular ilmenite ore also shows fine hematite lamellae intergrown in ilmenite. To concentrate the TiO 2, hematite and gangue silicates must be separated as much as possible from the ore.

Frontiers

The decreased ground size of ilmenite-bearing ores challenges the selectivity of collectors of ilmenite. Taking advantage of flotation tests and density functional theory (DFT), the selectivity of benzyl hydroxamic acid (BHA) and the adsorption mechanism of oleate and BHA on ilmenite were systematically investigated. The flotation tests showed that BHA had good selectivity to ilmenite. Get price
