Effect of TiO2‐content on Reduction of Iron Ore Agglomerates
The effect of titanium oxide on iron ore agglomerates is studied by the use of test sinter, test pellets and synthetic briquettes under laboratory conditions. Titanium favours secondary hematite rather than magnetite, which is the main phase in the sinter of Rautaruukkis Raahe plant.

Effect of titanium in iron ore Titanium additions were made using two different materials: rutile and crushed titanium-bearing haematite pellets. While both titanium additions clearly increased the RDI, titanium seemed to favour secondary haematite.
Sintering Characteristics of Titanium Containing Iron Ores
Titanium-bearing iron ores are found in many large deposits around the world and are becoming an important alternative source of iron ore due to the shortage of economic high purity ores. For instance, high titanium (and vanadium) magnetite concentrates account for more than 14%...
The Effect of Titanium on Reduction Degradation of Iron ...
The effect of titanium oxide in solid solution in magnetite on the magnetite to haematite transformation rate was studied first in order to simulate the final stage of the sintering process. In other experiments, haematite samples doped with 0.5, 2.0 and 5.0 wt per cent titanium oxide were studied using thermogravimetry...

EFfect of TiO2-content on Reduction of Iron Ore Agglomerates. The effect of titanium oxide on iron ore agglomerates is studied by the use of test sinter, test pellets and synthetic briquettes under laboratory conditions. Titanium favours secondary hematite rather than magnetite, which is the main phase in the sinter of Rautaruukkis Raahe plant.
Effect of Titania on Sintering Performance of Hematite ...
The effect of Titania (TiO2) addition on the sintering performance of hematite iron ore has been studied by doping pure TiO2 into a sinter blend. The results of laboratory scale compact sintering tests confirmed the considerable effect of TiO2 addition on the sinter strength and mineralogy.
CN105112689A - Method for extracting titanium from ...
The method of extraction of titanium vanadium titanium magnetite claim, wherein: the specific steps are as follows: a, smelting reduction furnace: The iron ore and coal with a reducing agent sodium or potassium additives, in the submerged arc furnace (or other direct reduction furnace) smelting reduction, vanadium, into the molten iron reduction,...
ILMENITE (Iron Titanium Oxide)
Magnetite is also similar and easily confused with ilmenite, but ilmenite has a different crystal form and is not as strongly magnetic. It is often associated with magnetite and therefore ilmenite is a minor ore of iron as the magnetite and ilmenite are processed for their iron contents.
Environmental Impact - Titanium
-soil is sent to factories where they take out the ore.-Ti found in rutile and ilmenite-extracted using electrolytic deoxidation process-heated to 1,652°F (900°C) and the subsequent stone reaction results in the creation of impure titanium tetrachloride (TiCl4)
Iron ore - Wikipedia
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. In 2011 the Financial Times has speculated that iron ore is "more integral to the global economy than any other commodity, except perhaps oil ".
Effects of Totally 48 Alloying Elements in Steel (Full ...
Titanium has a strong affinity with nitrogen, oxygen and carbon, also stronger affinity with S than iron, which is a good effective element for a deoxidizing agent and fixing nitrogen and carbon. Although titanium is a strong carbide forming element, it does not combine with other elements to form compounds.
Effect of Titanium Addition on Behavior of Medium Carbon Steel
Due to the high price of niobium and vanadium, the development of titanium microalloyed steels seems to be attracted and get more attention recently. Steel alloyed with titanium alone especially the forma- tion mechanism of TiC precipitation during different processes and its effect are seldom studied in …
Minerals | Free Full-Text | Effect of TiO2 on the ...
Hence, the reduction reactions of iron oxides and titanium oxides are obstructed due to the nonreactive minerals with increasing TiO 2 content. With the increase of TiO 2 content, the iron grade and the quantity of iron-bearing minerals decrease while gangue minerals of perovskite and Ti-bearing spinel Mg 2 TiO 4 increase. Moreover, under the same reduction condition, the increasing gangue minerals decrease …
Titanium - Rio Tinto
RTFT operates an open cast titanium dioxide mine at Lac Tio near Havre-Saint-Pierre and, at its metallurgical complex in Sorel-Tracy, extracts high-quality titanium dioxide feedstock, pig iron, steel and metal powders from the ore.
Titanium in the rapidly cooled hypereutectic gray iron ...
Apr 01, 2003 · The effect of titanium on the structure and properties of a rapidly cooled hypereutectic cast gray iron has been studied on the example of permanent mold (PM) casting. A microstructure study showed that titanium is a relatively strong element in controlling solidification structure by increasing undercooling and thus promoting type D graphite.
Volumetric Determination of Iron Assay by Reduction Method
The averages of their reports were :—Zinc reduction, 55.3 per cent, iron; and zinc sulphide, 55.4 per cent. A standard sample of titaniferous iron ore was analyzed by this method. It contained 60.49 % of iron and considerable titanium; 0.25 grm. was taken in duplicate, requiring (a) 27.10 cc. and (b) 27.08 cc. of decinormal permanganate.
Effect of Cyanide on Steel and How Iron Minerals are ...
Complex iron carbonate minerals, such as ankerite, are said to decompose to some extent in cyanide solutions of low alkalinity (below pH 10) forming ferrocyanides. The sulphide iron minerals decompose appreciably in cyanide solutions, however,...
Magnetite - Wikipedia
Magnetite is a rock mineral and one of the main iron ores, with the stone formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces ...
