Slag . The interaction of four types of commonly used refractories (, burned magnesite brick, magnesia carbon brick, corundum castable, and SiC castable) with slag formed in the smelting of titanium (wt. [TiO 2] = 80%) in an electric furnace at the Panzhihuan Iron and Steel plant was studied.
ilmenite slag plants in china allstartheatrecoza Titanium Slag – Tronox Overview Ilmenite is reduced in an electric arc furnace to produce high titania slag and iron The titania slag is cooled crushed screened and sized in a slag processing plant to produce chloride grade slag . Email:query
The influencing mechanism of oxygen volume percent (%VO 2) on the acid solubility of the titanium slag during the oxidization at 1273 K (1000 °C) are investigated.%VO 2 has marginal effect on the phase composition evolution, but greatly affects the microstructure evolutions during the oxidation, that is, increasing %VO 2 promotes Fe outward migration and further results in the formation of ...
Titanium dioxide (TiO2) has been widely used as pigment in paints, fillers for plastic and paper, coatings, adsorbents, cosmetics, catalysts, and gas sensors. A novel process for TiO2 production has been developed by the Institute of Process Engineering. This work develops the novel process by using the NaOH/KOH binary molten salt (50 mol % NaOH, 50 mol % KOH) instead of NaOH molten salt.
Titanium slag: market prices of acid dissolved titanium slag and high titanium slag dropped further in Feb. and many manufacturers stopped production during Chinese Lunar New Year and refused to ...
Jul 12, 2018· According to Neometals, the Chinese institute used for the test work has extensive experience in the processing and smelting of vanadiferous titanomagnetite ore systems, ... Neometals said that the results of smelting and slag cleaning produced a titanium slag that was potentially suitable as feedstock for titanium dioxide production.
There were two controlling factors, which should be kept balance of raw input and energy during titanium slag smelting in closed high power direct current electric arc furnace, DC furnace for short. The first factor contains compositions and ratio of input raw materials. Compositions of the raw could influence the progress and technical indicators of DC furnace smelting, and on the meanwhile ...
Aug 03, 2017· Also, the mineral phase of the meltingseparated titanium slag is stable, and has a compact structure. There is no mature process to deal with meltingseparated titanium slag at present. Only a small amount of meltingseparated titanium slag is used as a raw material to produce titanium dioxide pigment in sulfate process.
Titaniumrich slag A novel process for the extraction of iron, titanium, vanadium, and chromium from highchromium vanadiumbearing titanomagnetite concentrates is proposed. This process involves several steps: partial reduction of the concentrates, magnetic separation, hydrochloric acid leaching of the titaniumbearing tailing, and alkaline
An alternative route was proposed for preparing rutile titanium dioxide (TiO2) white pigment. The process involves the digestion of titanium slag with sulfuric acid, subsequent hydrolysis of unenriched titanyl sulfate solution with ammonia, lowtemperature calcination, and unseeded crystallization, producing a highquality rutile TiO2 white pigment.
duction of the titaniarich slag is further acidleached under a highpressure and moderatetemperature hydrometallurgical process to yield an upgraded titania slag with mass percent TiO 2, which is used in the chloride process. After describing in detail the beneficiation, chemistry, and mineralogy of the hemoilmenite ore, this
AM Stats: Chinese high titanium slag producers'' stocks down by % MOM [1023] AM Stats: Chinese high titanium slag producers'' sales up by % YOY [1022] AM Stats: Chinese high titanium slag producers'' output up by % MOM in Sep [1022]
Saudi Arabia: The Chinese General Contractor Chengdu Design Research Institute of Bldg Materials Industry Co Ltd in Chengdu has placed an order with Gebr. Pfeiffer SE for the supply of an MPS 3070 BC cement mill for Readymix in Saudi Arabia. The 1100kW drive power mill will grind 30t/hr of granulated blastfurnace slag and 46t/hr of Ordinary Portland Cement to a fineness of 4000cm²/g and ...
requires a pretreatment of titanium slag by fine grinding. It was found that grinding of titanium slag particles to 40 µm contributes to more complete decomposition of the anosovite with a formation of sodium titanates. It was found that during the sintering of titanium slag with soda at a mass ratio of slag:soda = 1:, decomposition of the ...
Jul 25, 2018· First, let''s take a look at the Titanium related products involved in the list, a total of 11 items. artificial rutile. Titanium ore and titanium concentrate, in addition to synthetic rutile. Titanium slag, titanium slag products containing more than 40% titanium. titanium dioxide
A Chinese Institute has expressed interest in technology transfer and investing in a titanium dioxide (pigment grade) manufacturing unit in Andhra Pradesh. The Institute of Process Engineering, a premier Chinese research institute has offered to give pollution free technology to convert titanium slag to pigment grade titanium dioxide to ...

In the present study, the titanium slag, used as the raw material to prepare titanium dioxide, is manufactured by smelting ilmenite in an electric arc furnace, with anthracite as reductants (Pistorius, 2002).In this process, the titanium slag was first decomposed in NaOH system at lower temperature.
To recover pigment grade TiO2, operating plants all over the world use chemical processes. Slagbased technology is considered to be attractive because of low waste generation and low chemical cost due to high titanium content and is poised to replace the conventional technology. This paper provides a review of the slagbased technology with the specific aim to produce leachable slag and ...
Owing to smelting vanadiumtitanium magnetite ore, the amount of iron entrainment in slag as droplets is far higher than that in conventional BF slag. However, the iron droplets can be easily settled by blowing air into the molten slag.
