Authors: Man Tang Ding. Abstract: Titanium concentrate and titanium slag were used to prepare high titanium ferroalloy to reduce cost. In the process, the 6-9% of aluminum consumption was replaced by magnesium. The reasonable slag system composition was used. The results indicate that the ferrotitanium of 75% [Ti] and [Al]<4% was prepared.

Commercial production will follow the project's trial start-up in the second half of 2016. The announcement delays previous project dates due to the scale of the project and safety and ...
mature titanium dioxide process, other methods are all in the stage of laboratory research. Recovery of titanium by sulfuric acid can not only treat titanium slag in large-scale, but also promote the process of direct reduction-electric furnace smelting by utilizing the titanium resource in the vanadium titanomagnetite concentrate. Therefore,
The smelting process at TTI involves the reduction of the iron oxides from the ilmenite with everything else reporting to the slag. The separation of the iron lifts the titanium dioxide content from approximately 54% in the ilmenite to approximately 87% in the slag. High-purity pig iron – a valuable co-product
The process of titanium slag smelting (High titanium slag and Acid slag) The finery of Micro carbon ferrochrome and de-dusting equipment (Smelting low carbon) The utilization on the equipment of hydrogen energy cracking (new energy and non-standard equipment) The equipment of Non-ferrous metal on holds smelting (Cobalt alloy copper and zinc powder)
Titanium slag in this study was produced by subjecting titanomagnetite concentrate to direct reduction-electric furnace smelting. Processing mineralogy and mineral phase reconstruction behavior at high temperature and slow cooling treatment were examined by chemical analysis, X-ray diffraction (XRD), optical microscopy (OM), scanning electron microscopy (SEM), and energy …
TiZir's TTI facility, located in Tyssedal, Norway, upgrades ilmenite to produce high-grade titanium slag and high-purity pig iron with an annual capacity of …
Fluxless smelting in a direct-current open-arc furnace is proposed as an opportunity to improve iron and vanadium recovery and potentially unlock the titanium as a slag product. Slags produced from a pilot study are compared to industrial slags produced from ilmenite.
Further processing, including smelting of ilmenite to produce titanium dioxide slag then takes place at the central processing complex in Empangeni, 20 km west of Richards Bay. KZN Sands produces ilmenite, slag fines, zircon, rutile, leucoxene, low manganese pig iron and chlorinatable titanium dioxide slag (see section 4).
