The combined pyro-hydro processes were investigated to modify the initial phases in the red mud and recover titanium values from the leach solution using organic solvents (Erçağ and Apak, 1997; Huang et al., 2016) or generate titanium enriched residue and simultaneously recover pig iron and sodium aluminate solution (Kasliwal and Sai, …

Titanium is made by a batch process. In the production of iron, for example, there is a continuous flow through the Blast Furnace. Iron ore and coke and limestone are added to the top, and iron and slag removed from the bottom. This is a very efficient way of making something. With titanium, however, you make it one batch at a time.

Keywords: vanadium titanium magnetite; titanium enrichment; alkalinity; melting temperature; carbon content 1. Introduction Vanadium-titanium magnetite is a complex symbiotic iron ore resource composed of iron, vanadium, titanium and other metals, which is one of the most important iron ore resources in China [1–4].

The specific experimental scheme of oxygen-enriched sintering of vanadium-titanium magnetite is shown in Table 4. Table 4. Experimental scheme. After the raw materials are prepared in accordance with the proportion scheme in Table 3, the materials are first artificially mixed evenly on an iron plate.

Dislocations are linear lattice defects in a crystalline solid. Since the unusual atomistic environment of the dislocation may greatly influence various material properties, control of the composition would offer more opportunities to obtain unique one-dimensional structures. In the present study, we have characterized the structure of dislocations in a …

Titanium metallurgy is the technology that extracts titanium metal and its compounds from titanium-bearing raw mineral. In 1791, a British pastor and amateur mineralogist, W. Gregor, discovered a new metallic element in a black magnetite (titanium magnetite). In 1795, the Deutsche chemist M.H. Klaproth also discovered this new …

Beach titanomagnetite was obtained from the Hainan Mining Corporation in Hainan Province, China. Chemical multi-element analysis of beach titanomagnetite was performed, and the results are shown in Table 1.With 55.51% iron and 7.86% TiO 2, the ore is low-titanium beach titanomagnetite (TiO 2 < 8%) [17]. Fig. 1 indicates that it contained …

The vanadium-bearing titanomagnetite (VBTM) ore deposit in the Panzhihua–Xichang region, China, is a complex ore that contains many valuable elements, including titanium (Ti), vanadium (V), iron (Fe), chromium (Cr), scandium (Sc), and gallium (Ga), and has high utilization value [1,2,3].Vanadium titanomagnetite concentrates …
