Extraction by other processes In South Africa a plant has been built to produce vanadium from titano- magnetite, where the pellets are roasted in a grate-kiln-cooler system. Sodium sulphate is used as chemical reagent and a process to evaporate the 98 vanadium containing solution.
ABSTRACT. In this study, a new vanadium extraction process from vanadium titano-magnetite(VTM) featuring calcification roasting and (NH 4) 2 C 2 O 4 solution leaching has been proposed. Compared with the traditional sodium roasting, the calcification roasting can avoid the production of waste gas and the sodium free tailings …
Titaniferous magnetite hard rock deposits are common throughout the world. Previously they have been processed to recover vanadium using the standard salt roast process, however the economics based on vanadium alone can be marginal due to the high CAPEX and OPEX, making it vulnerable in a volatile vanadium market.

Vanadium titano-magnetite (VTM) is a significant resource in China—analysis shows that China possesses approximately 10 billion tons of VTM. In this study, we characterize VTM's isothermal reduction mechanisms in the mixture of H2, CO, and N2 where the variables considered include reduction time, reduction temperature, …
Introduction. The vanadiferous titanomagnetite [VTM] deposits are the primary source of vanadium [V] in worldwide production, with Brazil as one of the most relevant producers of its oxide [V 2 O 5] (United States Geological Survey, 2017, Taylor et al., 2006, Habashi, 1997, United States Geological Survey and Commodity, 2020).Blast …
Vanadium titanomagnetite (VTM) is an important mineral for developing titanium resources, but the comprehensive recovery of ilmenite separation is extremely poor, resulting in the low-efficiency utilization of titanium resources. Here, the separation of ilmenite from VTM ore is studied by combining magnetic separation and flotation technologies. In …
