Materials. Table I shows the chemical composition of the ultra-high-titanium vanadium–titanium magnetite concentrate (<75 μm) used in the experiment. The data clearly reflect the mine's low-iron, high-vanadium, and ultra-high titanium characteristics. The X-ray diffraction (XRD) pattern of the raw ore in Figure 1 shows that the phases of the concentrate …
As mentioned previously, titanium is currently produced by the Kroll process In the reduction and separation stages, iron in the steel reactor diffuses into the titanium sponge and accumulates in the titanium product as an impurity.[67,68,69,70] In the current Kroll-based technology, the iron concentration at the bottom and side of the massive ...
Natural rutile was the feedstock of choice at the early years of the Kroll process, but nowadays it comes in limited supply. Titanium dioxide slags are produced by reduction smelting of ilmenite in electric arc furnaces. The slag grade (sulfate or chloride) depends essentially on the quality of the ore or concentrate fed to the slag furnaces.

Under the optimal conditions, 93.67% iron from the raw ore was recovered in the form of iron nugget with 95.44% iron grade. After a water leaching process, 85.61% of the vanadium from the roasting slag was leached, confirming the sodium oxidation of most of the vanadium oxides to water-soluble sodium vanadate during the roasting process. The ...

A trace amount of manganese, titanium, nickel, etc. can be found within their microstructure. Iron ore processing has its root in hematite (α-Fe 2 O 3), maghemite ... In the direct reduction process of iron ore where solid carbon is the reductant, self-reducing pellets, briquettes or composites entails iron ore embedded in coal or carbonaceous ...
Titanium is made by a batch process. In the production of iron, for example, there is a continuous flow through the Blast Furnace. Iron ore and coke and limestone are added to the top, and iron and slag removed from the bottom. This is a very efficient way of making something. With titanium, however, you make it one batch at a time.
The article discusses the main technologies for processing titanium-containing raw materials, and the advantages and disadvantages of various technological solutions.
The dosage of (NH 4) 2 SO 4 required for high iron leaching is a critical factor for the roasting process. The effect of the ilmenite ore-to-(NH 4) 2 SO 4 mass ratio on the leaching efficiency of iron and titanium loss was investigated under the following optimal conditions: roasting temperature of 500 °C, roasting time of 210 min, and ...
A plant in Australia processes ilmenite placer ore. The titanium in the ore is mainly ilmenite, followed by rutile, white titanium, brookite, and sphene. 4.91% of titanium is dispersed in iron-manganese minerals (goethite, pyrite, …
South African vanadium–titanium magnetite is a complex mineral resource rich in iron, vanadium, titanium, and chromium [1,2,3].Its ore composition is composed of more than 20 elements [4,5,6].It is the most complex ore of its type in the world and contains more than 10 valuable elements, so it has a very important integrated utilization value.
chloride process route, because the silica levels are too high and generally the concentrates are too fine to put in a fluidised bed. SOREL PROJECT Rio Tinto QIT (Murty. 2007) operations in Canada at Sorel-Tracy smelt hard rock titanium ore assaying 34% titania to produce titania slag and pig iron, as well as iron powder
Titanium metal production by the Kroll process requires a high-grade ore material as a feedstock for chlorination, such as natural or synthetic rutile. Electrochemical methods for making titanium have generally required even higher purity. This paper describes different methods for iron removal from a pseudorutile mineral sand for the eventual goal of producing …
This technique is highly efficient for the extraction of weakly magnetic materials and has been successfully applied in the processing of iron ore, titanium ore, and other valuable minerals. 3. **Dry Magnetic Separation**: …
Originally, the iron was collected in pools called pigs, which is the origin of the name pig iron. Figure (PageIndex{1}): A Blast Furnace for Converting Iron Oxides to Iron Metal. (a) The furnace is charged with alternating layers of iron ore (largely Fe 2 O 3) and a mixture of coke (C) and limestone (CaCO 3). Blasting hot air into the ...
The optimum solid/liquid ratio was 1:6 where the maximum leachabilities of iron and titanium were 67.71% and 64.78%, respectively. On increasing the ratio, a significant improvement in leachability of both titanium and iron was not observed. Another important parameter for the processing of ilmenite is the agitating speed.
