Beneficiation of ilmenite from lumar analog The results reported were obtained on a meteoric eucrite sample called Millbillillie Sample no. 173. Optical microscopy studies of the sample showed it to consist of ilmenite, troilite, and transparent gangue. The transparent gangue consisted of feldspar anorthite, pyroxenes, olivines, and opaques.
Chloridization is a potential method of beneficiating ilmenite. Studies on beneficiation of ilmenite were carried out by using titanium chloride as the chloridizing agent in a laboratory scale fluidized bed reactor. Experiments were conducted on 1, 10, and 36 grams per batch scale, and the effect of the various rate determining steps on conversion was studied.

Mineralogical studies performed by XRF, optical microscopy and Electron Probe Micro Analyzer EPMA studies indicated that ilmenite and apatite are main valuable minerals. The gangue minerals consist of the silicate minerals such as
Beneficiation of lunar ilmenite One of the most important commodities lacking in the moon is free oxygen which is required for life and used extensively for propellent. Free oxygen, however, can be obtained by liberating it from the oxides and silicates that form the lunar rocks and regolith.
Titanium and iron are closely related in nature, although titanium is the ninth most abundant element in the Earths crust. Iron in titanium ores must be removed for use as feedstocks in the manufacture of titanium dioxide pigments and pure TiCl4 for metal titanium. In this study, various beneficiation processes of ilmenite for production of TiO2 have been reviewed and compared.
In the first, which was carried out in an alkaline medium, the gangue minerals were removed from the float and the ilmenite concentrate was collected as sediment. The ore could be enriched to a maximum TiO 2 content of only 37 at a pH of 10.75, pulp density of about 150175 glitre and at a collector concentration of 1.25 kgtonne of ore.
An improved digester method and apparatus particularly useful in the digestion stage of a process for the beneficiation of titaniferous iron ores and the like. A discharge nozzle is connected to a portion of the digester and the digested material is pumped from the digester via a pump connected to the discharge nozzle. In one aspect, fluid from a fluid source is passed through a portion of the ...
Ilmenite mining process Most ilmenite ore are poor ilmenite ore, so the ore processing must be carried out. Ilmenite ore beneficiation methods currently used for the mechanical selection including washing, screening, reelection, high intensity magnetic separation and flotation, as well as fire enrichment, chemical processing method.
Aug 01, 2019 Ilmenite in sand ore is often produced with rutile, zircon, monazite, yttrium phosphate and so on. Titanium concentrate usually refers to ilmenite, which contains more than 46 TiO 2. Ilmenite Ore Beneficiation Plant. The ore dressing process of ilmenite depends on the nature of the material.

Sep 09, 2020 Ilmenite flotation technology. 09-09-20 489 Views icon 1 Ilmenite flotation technology . Ilmenite is brittle and dense. Due to the physical and chemical properties of the mineral surface, it is not easy to recover coarse-grained ilmenite, but fine-grained or fine-grained ilmenite has better floatability and can be recovered by flotation.
We claim 1. A process for beneficiating a weathered ilmenite ore, which comprises forming from the ilmenite under non-oxidizing conditions and without reducing more than 115 by weight of the iron content of the ilmenite, a material of which at least 20 by weight comprises pseudobrookite, reducing the said material to yield a material having at least 4 of its iron content calculated as Fe ...

Combination beneficiation ilmenite digestion liquor reduction process . United States Patent 4089675 . Abstract A process is disclosed ... As FeO, which is equivalent to the normal rutile chlorination feed and the resulting digestion liquor yields a good quality TiO 2 pigment.
Magnetic separation is mainly used for magnetic oxide minerals of ferrous minerals, such as magnetite, V-Ti magnetite, hematite and ilmenite, and also for pyrrhotite beneficiation. Magnetic separation is the concentration of ilmenite. It uses different permeability of various minerals to
Jul 26, 2017 3. FeTiO 3 concentrate, ilmenite. The beneficiation of ilmenites requires pyrometallurgical or chemical process steps to separate the iron content of approximately 30. There are some methods of iron separation from FeTiO 3, which vary in their technical and energy demands.

Ten metric tons of Longnose ilmenite sample was beneficiated using gravity and magnetic separation to produce an ilmenite concentrate for hydrometallurgical testing. The beneficiation process resulted in three final products high silica tailings, magnetitetitanomagnetite concentrate, and ilmenite concentrate.
Distinguishing features . Ilmenite is often recognised in many altered igneous rocks which is most, to some extent by the production of the white pseudo-mineral leucoxene.Often, ilmenites are rimed in leucoxene, which allows ilmenite to be distinguished from magnetite and other iron-titanium oxides. The example shown in the image at right is typical of leucoxene-rimed ilmenite.
