is the main to produce moreover hematite, magnetite and rutile may be found in , these oxides have been reported as arsenic sorbents. The aim of this work was to study the performance of the to both arsenic species in water at natural pH and aerobic conditions at low and high arsenic concentrations 150 and 1500 ?g/L.
Several . After the of any highly magnetic research groups have attempted to lower the chromia susceptible material, they used a low temperature roast levels in Murray Basin concentrates with a at 450–600uC to obtain a product with 54?4 wt-% TiO2 magnetising roast.
is the primary ore , a metal needed to make a variety of high-performance alloys. Most of the mined worldwide is used to manufacture dioxide, IiO2, an important pigment, whiting, and polishing abrasive. has a high resistance to weathering.
An improved process is described for producing dioxide -type ore. The ore is digested with aqueous hydrogen fluoride, the resulting liquid mixture treated with a water-soluble oxidizing agent, and the ferric iron impurities, in the resulting digestion solution, at a pH between about 1.0 and 6.0, are extracted out with a mono-or dialkyl, or mono- or di-alkylphenyl ...

FeO.TiO2 with some of the contained Ferrous Oxide oxidised to Ferric Oxide, leaving various iron oxides and Dioxide and having total elevated TiO2 contents between 55-65 wt.%. SG: 3.5- 4.5: Anatase: A natural occurring mineral dioxide in crystallographic containing in excess of 90% TiO2. SG of 3.9. Bitumen
, iron-black, heavy, metallic oxide mineral, composed of iron and oxide FeTiO3, that is used as the major source . It forms solid-solution series with geikielite and pyrophanite in which magnesium and manganese, respectively, replace iron in the crystal structure.
Domestic and perovskite re sources were estimated in 1983 to contain 31 million short tons st , in addition to rock deposits scattered throughout the country 1. The demand in the United States in 1983 was 523,000 st 1. Most of these ma terials contain too much Ca, Mg, and Mn
separate iron from titanium. The titanium slag is then leached with sulfuric acid or with hydrochloric acid at elevated temperatures. 2 Reduction of ilmenite to convert ferric iron partially to the ferrous form or completely to the metallic iron form followed by acid leaching.
Overall recovery to the concentrate stream was estimated at 64%. The CTL process contains five major process steps: atmospheric , oxidation, extraction/precipitation/calcination, extraction/precipitation/calcination, and recycle of raffinate back into the leaching stage.
Ilmenite 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.
· Ferrotitanium is prepared by smelting or rutile with iron and coke in an electric furnace, used as a scavenger in the steel industry to oxygen and nitrogen from steel. In chemistry , oxide TiO 2 is extensively used as white pigment due to its excellent covering power, which is prepared along the same route of metal ...
Solutions of FeTiO 3 and a titaniferous slag, in fused Li 2 O. 2B 2 O 3 and Li 2 O. 4B 2 O 3, yield on cooling compounds tentatively identified as LiFe 2. 5 Ti 3 O 9 and Li 2 Fe 3 Ti 2. 5 O 9 respectively. Both compounds are orthorhombic, and have the pseudobrookite structure. The solutions yield, in addition, rutile TiO 2.The yield of rutile increases from about 1 to 24% ...
