The results indicated that the electrolysis of magnesium chloride and the smelting of titanium slag accounted for 39.6% and 22.4% of the total impact of Kroll process, respectively. The accumulative energy consumption of the titanium sponge production in China was 423 GJ/t. Electric power accounted for 66% of the accumulative energy consumption.
Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.
(Nayl et al., 2009). In spite of high power consumption, smelting of ilmenite or titanium-bearing ore has several advantages over the synthetic rutile route by chemical process. The major advantages of the slag technology are: high titanium content, low waste generation, being suitable for sulphate and chloride processes, low chemicals
Process mechanisms in ilmenite smelting 654 DECEMBER 2004 The Journal of The South African Institute of Mining and Metallurgy Figure 1—Liquidus diagram for the TiO2-FeTiO3-Ti2O3 system excluding Magnéli phases. Broken lines indicate isothermal slag/(slag + Fe°) boundaries.
the electric furnace titanium slag had higher content of TiO2. The primary phase of commercially produced titanium slags is CaTiO3, and thus, it is difficult to recover titanium from the titanium slags due to the poor acid solubility of CaTiO3. Therefore, the titanium slag composition, which is beneficial for electric smelting,
Slag stripping 2-stage smelting process • 1st stage: high-purity pig iron and 86% TiO2 slag (when applied to ilmenitesmelting) • Hot slag transfer to stripping furnace • 2nd stage: high-grade slag (>90% TiO2) and impure metal

The invention discloses a method for extracting titanium from vanadium-titanium magnetite. The method comprises the following steps: adding sodium or potassium salt additive in the reduction smelting of an iron ore concentrate electric stove to obtain liquid iron and titanium-containing slag, wherein vanadium and iron are reduced to enter liquid iron, under a smelting high temperature ...
Smelting process. The smelting technology used at RBM was originally developed and proven at Quebec Iron and Titanium (QIT Fer et Titane) in Sorel, Canada, where coarse ilmenite is smelted to produce a high-TiO 2 slag and pig iron in similar furnaces. This technology was adapted for RBM to process the fine ilmenite concentrate mined on the ...
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 dedicated for fluidizing chlorination and fused aslt chlorination, and acid slouble slag dedicated for sulfate, and acid soluble slag dedicated ...

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.
according to analyzing and summarizing the literature of ilmenite concentrate smelting titanium slag, comes to conclude: the production process of ilmenite concentrate smelting titanium slag can be divided into the one-step method and two-step method, dominated by two-step method at home; foreign dominated by two-step. This paper introduces the main content of one-step method and two-step ...
Separating titanium from slag by gravity separation or flotation process. High titanium slag is formed after the physical production process of titanium ore enrichment material, through the electric heating and melting of titanium, the enrichment of titanium in the titanium dioxide and iron melting separation obtained TiO2 content high concentration. . High titanium slag is not waste residue ...
A method of preparing a pre-reduced ilmenite ore for smelting, wherein metal oxides contained in the ore are selectively reduced in solid-state reactions over titanium oxide, the method including the step of pre-reducing carbon-based pellets of the ore.
Smelting Smelting is a process of melting and separation of the charge into two or more immiscible liquid layers,which may be slag, matte, speiss or metal. The di!erent types of smelting are: (i) reduction smelting; (ii) matte smelting; and (iii) ﬂash smelting
Primary production of lightweight metals such as titanium is an energy-intensive and expensive process that results in significant carbon dioxide (CO 2) and other emissions.Lowering the energy consumption, cost, and emissions associated with processing titanium would make it more competitive with incumbent structural metals such as steel.
process, is therefore one of the primary objectives of ilmenite smelting. Slag and iron are tapped periodically from separate sets of tapholes located around the circumference of the furnace. The slag tapholes are on a higher elevation than those for iron. Slag is tapped into 20 t steel pots, and cooled for
Sep 30, 2010· Smelting is a very different process than forging. You should look for a metal casting forum. Not to say somebody hear could probably give you a decent idea of what you would need to do. Why do you want titanium hammer other than the cool factor? Steel is really the ultimate material for hammers because it has more mass for volume and it is ...
