A comparative study on the chloride effectiveness of synthetic rutile
Ilmenite(FeTiO 3) ore is a raw material for producing TiCl 4 through the chlorination method and the sulfuric acid reaction method. TiCl 4 is used as a raw material for producing metallic titaniumindustrial one or an ore, e.g. rutile is an ore for the titanium mineral and an industrial one when for its high refractive index and colour, used as a white pigment. Diversified industries need minerals as raw materials with a wide price range, e.g. the high market rate of industrial diamond is in per gm or kg whereas 17 CHAPTERINDUSTRIAL MINERALOGY: MINERAL PROCESSING,

Analysis of the current technical solutions for the processing of iron ores showed that the high-grade ores are directly exposed to metallurgical processing; by comparison, low-grade ores, 2.2.1 Occurrence. Rare earth minerals occur as fluorites, oxides, tantalates, carbonates, phosphates, sulfates, borates, silicates, etc. (Qi 2018).List of different rare earth minerals are presented in Table 2.3.The average concentration of REEs in the earth’s crust is found to be 150–220 ppm, which is much higher than the concentration of Mineral Processing of Rare Earth Ores SpringerLink

The ratio of bastnaesite to monazite in the deposit is approximately 3:1, and REEs are recycled from iron ore processing tailings. 42, 43 There are three mining areas in the Bayan Obo deposit. The Main Ore Body and West Ore Body were mined by Baotou Iron and Steel Group in 1957, and the West Ore Body was exploited in 2004. 5. In this study, the production of synthetic rutile from tin ore beneficiation by-products from Bangka Island, Indonesia contained about 46% of TiO 2 via pre-oxidation and reductive leaching in hydrochloric acid was investigated.

The production of raw titanium metal relies on natural and man-made feed materials, including natural rutile, titanium dioxide slags of different grades (“chloride slag,” UGS, and “sulfate slag”), and synthetic rutile. Natural rutile was the feedstock of choice at the early years of the Kroll process, but nowadays it comes inMinerals, slags, and other feedstock for the production of

Advances in Beneficiation of Low-Grade Bauxite SpringerLink
Bauxite is the major alumina (Al 2 O 3 ) bearing ore used in the aluminum manufacturing industries. The bauxite containing less than 50% Al 2 O 3 is called low-grade bauxite ore which is commonly used for the alumina -based abrasives and refractories productions. The alumina -silica and alumina -ferrite complexes are the foremost From the slopes of these straight lines, it was found that the activation energy of these reactions ≈ 123 and 136 kJ /mole (Fig. 9), for reduction of ilmenite with coke breeze in the form of(PDF) KINETIC REDUCTION OF ROSETTA ILMENITE WITH

Physical beneficiation of heavy minerals ScienceDirect
The efficiency of physical separation techniques of heavy minerals usually encounters some set-backs. The reason is often not far from the inability to develop suitable mineral characterization strategies in order to comprehend/evaluate certain physicochemical features such as surface chemistry, specific gravity difference, magnetic and electrical The reactivity of ilmenite ore during leaching with hydrochloric acid can be greatly enhanced by reduction in solution using metallic iron. Addition of a particular amount of iron powder after a certain time of reaction will reduce all the dissolved Fe 3+ to Fe 2+ and reduce a portion of the dissolved Ti 4+ to Ti 3+.As the leaching continues, any further Reductive leaching of ilmenite ore in hydrochloric acid for
