Ilmenite is an oxidized mineral of iron and titanium. It is the raw ore for extracting titanium. Ilmenite has a wide range of uses and can be processed into titanium dioxide powder, various titanium-containing compounds, wear-resistant ceramic materials, magnetic materials, etc. Iron-containing waste residue can also be applied to make …
To develop a flowsheet for separation of high grade titanium-rutile from ilmenite, that will meet market requirements. Rutile has a SG of 4.2, hardness 6.0 to 6.5 and is non-magnetic; while ilmenite has a SG of 4.5 to 5.0, hardness of 5.0 to 6.0, and is weakly magnetic.
Rutile (TiO2) is a vital industrial material used in pigments and in many other valuable chemicals. A new production process to synthesize rutile from natural ilmenite ore and therefore overcome the environmental problems associated with conventional rutile extraction processes was developed. Because the simple phase separation of ilmenite …
This process uses nascent hydrogen generated by the reaction of a base metal like Al with diluted H2SO4 at moderate temperatures together with ilmenite concentrate in a specific milling and ...

Pitfield represents a newly recognised type of stratabound sedimentary rock-hosted titanium deposit, unlike the more common beach sand and hard-rock types of titanium deposits found globally. Initial petrography work confirms the presence of ilmenite, a titanium-iron oxide mineral, which is highly valued as a source for titanium oxide and …

The mineralogical composition of the ore (commercial ilmenite), obtained by XRD, is characterised by a high concentration of ilmenite (FeTiO3), 70 ± 6 %, compensated by …
Ilmenite in anorthositic host rock. Blåfjell mine, Rogaland, Norway. The sample is from an abandoned mine, but not far from Blåfjell is a working Tellenes mine (picture below). ... Some grains demonstrate half-completed leucoxenisation process (few examples are annotated). The width of the view is 3.8 mm.
Kahnoj ilmenite rock deposit with 7.5% TiO2 was crushed and concentrated. The resulting concentrate had 39.5% titanium dioxide. Then, the concentrate's grade was further improved by slagging process.
Hard rock ilmenite and heavy mineral sands are the two major raw materials used to recover titania and titanium. The term ilmenite, as used by the Titanium industry, covers both hard-rock ilmenite, ... the sulphate process, ilmenite and titanium slag are leached with sulphuric acid. In the chloride process, titania pigment and titanium metal ...
Ilmenite is the iron–titanium oxide mineral with an idealized composition of FeTiO3 (FeO·TiO 2), which is usually used as the main source of Titanium dioxide. The …
The ilmenite conversion process has been broken down into three general unit operations¬-reduction, smelting, and leaching—as shown in figures 8, 9, and 10. To see what actual flow-rates and energy requirements may be expected in a production plant, material and energy balance data from the 4.5- to 9.1-kg/h pilot plant were scaled to a …

Therefore, slag produced from rock ilmenite is mostly sold to TiO 2 pigment producers that use the Sulfate process, hence the name "sulfate slag." Sulfate slag cannot be used in fluid bed chlorination because it contains significant amounts of alkali earth oxides (CaO and MgO), which, as explained in Chapter 4, can cause severe …

Titanium is basically found in nature as ilmenite ore (FeTiO3) either as a rock or as sand, rutile, anatase and brookite, which although they all have the same formula (TiO2), but differing ...
In this ilmenite rock, there is a cementation process where the sediment grains stick together with other minerals which may come from groundwater or the result of dissolving minerals in the sediment itself. The cementation material can be carbonate (CO 3), silica (Si), or iron oxide (Fe).
Furthermore, during the mining and the grinding process that the rock ilmenite has undergone prior to exposure, the material may have accumulated mechanical stress. The further thermal and chemical stress during exposure to the conditions in the combustion chamber, adds to this accumulated stress and leads, most probably, to …
4. Electric-separation method is mainly to deal with the coarse concentrate containing titanium pyroxene and other non-conductive impurities produced by gravity separation and magnetic separation. It is widely used in the selection process, and the electro-separation method has requirements on the particle size of ilmenite. The lower …
Pilot-Scale Demonstration of Ilmenite Processing Technology Submitted by: Matthew Mlinar, Program Manager, Mineral Processing Shashi Rao, ... A rock ilmenite concentrates from New York and Minnesota containing about 46-47 % TiO2 was smelted in an electric arc furnace with coke, woodchips, and soda ash to separate the iron as pig …
Analysis using the X-Ray Diffractometer (XRD) shows that the ilmenite rock consists of the ilmenite (FeTiO 3) mineral phase of 43.78%, the calcite mineral phase …
Figure 1. Ilmenite Banten XRD Analysis -100+150 mesh (MS 31) 3.2. Characterization of Caustic Fusion and Acid Leach TiO 2 The extraction process of titanium dioxide (TiO 2) in this study was conducted by the steps of the Banten ilmenite sieving process using a sieve with a mesh size of 100 and a mesh of 150.
