1. Introduction. Vanadium, the 23rd element in Mendeleyev's periodic table, was first discovered in 1801 within a lead vanadate ore by Andrés Manuel del Río, but it was mistakenly identified as chromium then (Habashi, 2002).The element was rediscovered in 1831 within converter slags from certain iron ore by Swedish chemist Nils Gabriel …
As the majority of vanadium is added to steel, the annual demand for vanadium tends to follow the annual demand for steel (Leont and Shavrin, 2000, Raja, 2007).Stricter regulations around the use of high-strength steel have however increased the demand for vanadium as a steel additive (Anon, 2011).The remainder of vanadium is …

Vanadium-titanium magnetite ore (VTM) is one of the important titanium ore. Especially in China, more than 90% of the titanium ore is VTM. 1–3 Nowadays, the iron and vanadium in VTM have been efficiently extracted by the steel-oriented traditional blast furnace technology. However, about half of titanium in VTM is discharged and …
The ore which contains 57.5% Fe, 0.66% V and 16.6% TiO2 was subjected to selective reduction smelting so that most of the iron reported to the metal phase and the …
Iron ore tailings (IOTs), a typical hazardous solid waste, seriously threaten human health and the ecological environment. However, the abundance of quartz, particularly in high-silica IOTs, renders them useful. Yet, state-of-the-art technologies have rarely reported the preparation of high-purity silica from high-silicon IOTs. Thus, this study proposed an eco …
