1. Introduction. China is rich in titanium resources, most of which are stored in Sichuan province in the form of vanadium‑titanium magnetite ore (Du, 1996).Generally, vanadium‑titanium magnetite concentrate including Fe of 30%, TiO 2 of 10%, and V 2 O 5 of 0.3% is smelted by using blast furnaces. Metal iron is separated from titanium by …

blast-furnace technology for the melting of the titanium-vanadium-magnetite concentrate suitably prepared in the form of sinter or pellets. vanadium in the titanium-vana-dium-magnetite concentrate does not prevent it from being directly used for the blast-furnace charge. Titanium, if intro-duced to the blast furnace in excessive amounts, may cause
Section snippets Materials. The material used in this study was a powdered natural magnetite ore (containing 94.45% Fe 3 O 4, wt/%).The XRD pattern of the material is shown in Fig. 2, indicating that the main phase structures were magnetite (Fe 3 O 4) and quartz (SiO 2).The chemical composition is presented in Table 1, which suggests that …
For carbon neutrality, the use of sinter should be decreased owing to higher CO2 emission in the sintering process of the blast furnace operations. This trend might …
Magnetite iron ores were routinely smelted during the second millennium CE. • Most contain more than 2% TiO 2 and cannot be used as ore for modern blast furnaces.. Bloomery iron smelting technology can use iron ores with up to 25%.
The minimum long-term iron ore price (62 per cent Fe) that would be required to underpin such a project is estimated at US$78/t CFR for BF-grade magnetite and US$68/t CFR for DR-grade concentrate.Apart from the financial benefits, it is demonstrated that the use of magnetite concentrate in ironmaking has the potential to reduce CO2 …
The V-Ti-Magnetite ore (VTM) is one of the special metallurgical resources and plays a vital role in the blast furnace (BF) ironmaking process in China because of its large reserves.[1,2,3] During the smelting process,[4,5,6] the proportion of VTM used in the BF is only about 65 pct; as a consequence, the TiO 2 in the BF slag is about 22-23 mass …
In India, the use of iron ore pellets in the blast furnace, electric arc furnace, or sponge iron production is continuously optimized, considering different aspects of the production chain from ...
