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 hode. A frozen lining is ...

A process as claimed in claim 7 in which the step of controlling the operation of the furnace includes estimating a slag titanium dioxide composition and pig iron carbon content composition as a function of the estimated frozen lining thickness and furnace wall temperatures, the calculated heat changes, the feed and product compositions and temperature measurements, the furnace gas composition ...
· The slag process used by QIT consists of reduction smelting ilmenitecoal mixtures in an electric arc furnace to separate about 85 pct of the iron as byproduct pig iron and to produce titanium slag containing about 72 wtpct TiO2, 13 wtpct FeO, and other oxide impurities. In 1975, QIT produced about 900,000 tons of titanium slag. QIT has recently built a commercial smelter at Richards Bay in ...
In the process of beneficiation, it is used for the magnetic roasting of lean iron ore so that the original weak magnetism of the ore changed to strong magnetism, which is good for magnetic separation. In chemical industry, rotary kiln is used for baking soda, calcining phosphate fertilizer, barium sulfide, titanium dioxide, etc. It has the ...
· natural form and also to manufacture titanium slag and synthetic rutile products as we will see later, Section Main Deposits The geology of titanium mineral deposits was reviewed by Force [8], and their world production and reserves has been summarized by Gambogui in different years (2009, 2010, and 2011) [4] [9] [10]. More than half of the world's titanium production is from ...

· The production of raw titanium metal relies on natural and manmade 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 in limited supply. Titanium dioxide slags are produced by ...
· To understand the desulfurization process during the refining of Crcontaining steel grades, this work was initiated to study the reactions between Crsulfur and chromiumcontaining slags. The sulfide capacities of CaOSiO2CrOx pseudoternary slags were measured using the traditional gasslag equilibration technique between 1823 K and 1923 K. Sixteen different slag compositions were .

Based on the current world advanced 30MW full closed DC arc furnace titanium slag continuous smelting production line, the high titanium slag project should develop a new product which can meet the requirements of downstream such as chlorination slag dedied for fluidizing ...
furnace inline layout is illustrated in Figure 2. The unit shown illustrates a twoinline submerged arc furnace configuration, which had been sold to a Brazilian client for the production of FeNi. With a power rating of 120 MVA and a hearth dimension of m x m, the smelters represents the world largest submerged arc furnaces ever ...
· reduction process into titanium slag production and is the. world's first enterprise that adopts the two stage method in. titanium slag production. The ilmenite p ellets are prereduced.
This concept would utilise waste material from steel industry, and spare the natural resources used for conventional PCC TETRACHLORIDE PRODUCTION BY THE, Chloride Process In the chloride process, rutile or highgrade ilmenite is converted to titanium tetrachloride (TiCl 4) gas. The conversion takes place in a chlorinator (, fluidized bed reactor) in the ...
ProspectThe FFC Cambridge process is now being developed for production of titanium and tantalum at scales of commercial significance by spinout companies of the University of Cambridge that have been specially established for commercialisation of the FFC Cambridge process (Schwandt et al., 2010;Fray, 2013). Pending on commercial development, the process has shown a wide spectrum of ...
Sulfide capacity increases with increasing basicity. This is a general trend telling about changes in slag network structure, its breaking and generation of more free oxygen ions O 2 − which are necessary for binding sulfur. Somewhat surprising is that binary oxides .
A method of processing slag, including the crushing and separation into fractions up to 5 mm and more than 5 mm, pneumatic classifiion and magnetic separation separation products, characterized in that the magnetic separation of each fraction of the slag is carried out separately with the production of standard metal, middlings and clean slag, while magnetic separation of slag fraction of ...
The invention discloses a method for extracting titanium from vanadiumtitanium magnetite.
