2021-11-1  Vanadium titanium magnetite (VTM) is a kind of composite mineral containing multi-component metals (such as Fe, V, Ti, Co, Cr, Mn, Ni, etc.), in which Fe, V, and Ti are the main elements. Therefore, VTM not only provides iron but also has an important comprehensive utilization value (Li et al., 2016).

Thermodynamic Analysis of Titanium Removal from

High purity iron is obtained from vanadium-titanium magnetite (VTM) by one-step coal-based direct reduction-smelting process with coal as reductant and sodium carbonate (Na2CO3) as additives. Industrial experiments show that the process of treating molten iron with a large amount of Na2CO3 is effective in removing titanium from molten iron.
