In the process for producing titanium slag from ilmenite as shown in Fig. 1, a mixture of ilmenite and coal and/or char is fed from bins 1, 2, 3 onto a roller feeder 4 or equivalent feeding device and supplied to a gastight double pendulum valve 5 and from there to the entry section of a reduction reactor 6, in particular a rotary kiln. The ...
Ilmenite is mostly mined for titanium dioxide production. Finely ground titanium dioxide is a bright white powder widely used as a base pigment in paint, paper and plastics. Ilmenite sand is also used as a sandblasting agent in the cleaning of diecasting dies. The world consumption of Ilmenite rises approximately 5% to 8% every year, with ...
Ilmenite, also known as manaccanite, is a titaniumiron oxide mineral with the idealized formula FeTiO is a weakly magnetic black or steelgray solid. From a commercial perspective, ilmenite is the most important ore of titanium. Ilmenite is the main source of titanium dioxide, which is used in paints, inks, fabrics, plastics, paper, sunscreen, food and cosmetics.
Electro Smelting of Ilmenite for Production of Tio 2 Slag – Potential of India as a Global Player 827 in reduction of a portion of the Ti to Ti 2O3, which is less soluble in sulfuric acid and hence such slags are not suitable for the sulfate process pigment production.
Synthetic rutile is produced from a titaniferous slag derived from ilmenite. Ilmenite concentrates are reduction smelted to remove iron as a high grade pig iron byproduct and to enrich the remaining slag phase in titanium. Oxidation of the slag and aging at high temperature in the presence of a titanium pyrophosphate flux converts the titanium bearing phases to discrete rutile crystals and a ...

Ilmenite is further upgraded to titanium dioxide to be used in paper, plastic, paint colour and cosmetic industries such as sunscreen. According to a 2011 report of ministry of mines, Odisha has third largest deposit of ilmenite in the country. Andhra Pradesh has the biggest deposit followed by Kerala and Tamil Nadu at the second spot.

RRL Bhubaneswar has been working on thermal plasma processing of ilmenite. In such static bed dc plasma reactor, the energy consumption was found to be about 3–4 kW h kg21 of ilmenite for conversion to 7 shows the reserve in India. Fig 7 resources of ilmenite and rutile in India VIII.
Titanium dioxide pigment of anatase crystal structure containing to % Nb 2 O 5, to % K 2 O, to % Sb 2 O 3, to % P 2 O 5 and the balance substantially TiO 2 ; the particles of said pigment having a surface coating of hydrous metal oxide, such as alumina. Such pigment is useful as a delustrant in synthetic fibers, such as cellulose acetate.
do not occur in ilmenite ores. After the slag is air quenched, it is crushed and ground to produce fine and coarse products [5 and 6]. These products are used in the downstream processing for the production of titanium dioxide pigment. The effect of heat treatment on Tislag was studied to understand the mechanism of upgrade
Abstract. Leaching with sulfuric and hydrochloric acids for upgrading titanium slag obtained from the Qaraaghaj ilmenite concentrate to a high grade titanium dioxide (TiO 2) was studied. The titanium slag containing % TiO 2 and % Fe 2 O 3 was leached at varying solid/liquid (S/L) ratio, particle size, leaching time and acid concentration.
ILMENITE AND RUTILE India is endowed with large resources of heavy minerals which occur mainly along coastal stretches of the country and also in inland placers. Heavy mineral sands comprise a group of seven minerals, viz, ilmenite, leucoxene (brown ilmenite), rutile, zircon, sillimanite, garnet and monazite. Ilmenite ( 2) and rutile (TiO 2
Titanium Dioxide. Titanium dioxide occurs naturally in the minerals rutile anastase, and ilmenite. The compound has many uses, most of which are related to its brilliant white color. It is used as an ingredient in paints in which it is the opaque covering agent even though the paint may have color as the result of added pigments.
Technology in Indian Titanium Dioxide Industry DSIR. In India the titanium dioxide industry arrived almost with the dawn of independence KMML have setup a plant to manufacture titanium dioxide by chloride process Digestion of Ilmenite or Titania Slag in Sulphuric Acid ii .
37 Slags from Ilmenite Products that are reasonably high in titanium dioxide (, 70 to 90 percent) can be produced from ilmenite by smelting to reduce the iron oxide content to metal leaving the titanium in the slag as oxide.

The ilmenite, as mined, has a high Cr2O3 content and is not suitable for direct smelting to titania slag. Titanium slag is produced in the mining, refining and smelting of mineral sands to produce titanium dioxide (TiO2) feedstocks used in the production of pigments, titanium metal, welding fluxes and other specialised products.
convert ilmenite or titanium slag to titanium dioxide. In this process, ilmenite and titanium slag are leached with sulfuric acid, and large quantities of waste and toxic byproducts are produced, resulting in serious environmental problems [4,5]. In the chloride process, titanium dioxide pigment is produced from rutile, titanium slag and some ...

A process is provided for the production of titania rich slag from ilmenite. The ilmenite is fed together with carbonaceous reductant, and in the absence of fluxes, to the molten bath of a arc furnace. The molten bath of the furnace forms the anode and one or more electrodes in the roof of the furnace forms the cathode. A frozen lining is established and maintained between the refractory ...
