During the past year, work on characterizing lunar material that has the potential of becoming ilmenite lunar ore was performed. The important aspects of any such material are that it has abundant ilmenite and that the ilmenite be easily separated. The final result sought is a pure (greater than 99 percent ilmenite) concentrate that will be used as feed …
In the beneficiation process of beach sand, ilmenite is removed by LIMS separation, and monazite is upgraded by HIMS separation. In the evaluation and feasibility verification of a placer deposit in North Korea, magnetic separation with different magnetic field strengths was used to selectively recover monazite/xenotime (magnetic field …

The ilmenite concentrates generated at this operation are sold under a 10 year contract to E. I. du Pont de Nemours and Co. for manufacture of pigments.
developed for beneficiation of lunar regolith to separate Ilmenite from the rest of the particles in the lunar regolith and produce an enriched feedstock that can be further used for extraction of oxygen and/or other metals. 2. Beneficiation test setup The beneficiation test setup is a multi-stage processing unit that
2. The jaw crusher crushes 50-230mm iron ore into the fine jaw crusher. Spiral washing machine is suitable for cleaning 0-50mm materials. 3. The fine jaw crusher crushes the material to 0-20mm. The vibrating screen sends the 0-20mm material into the ball mill, and the +20mm material returns to the fine jaw crusher.
The ilmenite concentrate recovered from red sediment sample by physical beneficiation process, which included scrubbing, desliming, gravity concentration, magnetic and electrostatic separation contains 99.2% grade with 92.2% recovery. The microscopic studies on ilmenite reveal that the ilmenite grains are seemed to be sub rounded, …
The addition of sodium ferrate increases ilmenite's surface active sites and enhances the interaction with sodium oleate. The recovery of ilmenite can be increased from 62% to more than 90% at pH 6. After ferrate treatment, the surface Zeta potential of ilmenite becomes more positive, and the isoelectric point (IEP) increases from pH 5.5 to …

Natural Ti‐Rich Mineral (Ilmenite, Titanite and Perovskite) Reference Materials for In Situ Ti Isotopic Measurement by LA‐MC‐ICP‐MS - Liu - 2024 - …
The ilmenite concentrate recovered from red sediment sample by physical beneficiation process, which included scrubbing, desliming, gravity concentration, magnetic and electrostatic separation, contains 99.41% grade with 97.3% recovery. The ilmenite mineral concentrate recovered from red sediments is also suitable for industrial …
United States Patent 3875286 . Abstract: An ilmenite ore may be beneficiated by converting the ore into a pseudobrookite-containing material, reducing that material to …
Beneficiation: The beneficiation of ilmenite from lunar rocks and soils is a case-in-point. Terrestrial ilmenite virtually always contains some Fe3+, typically in the form of exsolved magnetite, giving the ilmenite a high magnetic susceptibility. Our detailed studies of the magnetic susceptibilities (MS) of the mineral and glass components of ...
The ilmenite grains are characterised by TiO2 content between 34.2 and 52.8 wt-% with low levels of impurities. The garnet geochemistry is more variable but dominated overall by almandine-rich ...
CESTAT Chennai held that the appellant has undertaken beneficiation process to make sand into processed/upgraded Ilmenite. Hence, export duty at rate of 5% FOB payable on such Ilmenite which …
Highlights. •. The future utilization trend of titanium resource will be largely relied on ilmenite. •. Combined processing technologies will be more effective in …
Magnetic beneficiation of lunar soils We will present a review of recent laboratory results obtained in dry magnetic separation of one gram samples of the minus 1 mm size fraction of five lunar soils of widely differing maturities. Two highland soils were investigated as potential sources of low iron content feed stocks for space manufacture …

The possibility of ilmenite ores beneficiation from the Ha Tinh deposit (Vietnam) by electrostatic and electromagnetic separation methods was carried out. The ilmenite concentrates obtained as a result of beneficiation can be used for further processing to obtain pigment titanium dioxide or titanium metal in a compact or in powder form.
The beneficiation of lunar plagioclase and ilmenite ores to feedstock grade permits a rapid growth of the space manufacturing economy by maximizing the production rate of metals and oxygen. A beneficiation scheme based on electrostatic and magnetic separation is preferred over conventional schemes, but such a scheme cannot be …
