“…More than 90% of produced vanadium is added into steel as an intermediate alloy in the form of ferrovanadium (e.g., FeV50, FeV60, FeV80), which is mainly prepared by the self-propagating high-temperature synthesis (SHS) process with a mixture composed of vanadium oxides, reducing agents and fluxing agents [20]. The SHS process is also known as combustion synthesis and involves combustion modes and thermal explosion modes through chemical reactions, which are widely applied to the preparation of master compounds and alloys [21][22][23][24]. The SHS technology is propelled by the heat release from chemical reactions completely or partially, and nearly no external heat sources are needed.…”

A novel high-efficiency industrialized clean production technology based on multi-stage gradient batching and smelting was proposed for the production of high-quality ferrovanadium. The thermodynamic mechanism of aluminothermic reduction equilibrium, alloy settlement and raw material impurity distribution were confirmed, and a multi-stage double-gradient aluminum addition pattern (DG-ADP), the highly efficient separation of molten slag and alloy, and typical impurity control standards of raw materials were achieved on the basis of a self-propagating high-temperature synthesis with an electric auxiliary heating (SHS-EAH) process. The reduction efficiency, separation efficiency and the comprehensive utilization rate of the secondary resources were significantly improved, as the whole total vanadium (T.V) content in the industrially produced residue slag reduced from 2.34 wt.% to 0.60 wt.%, while the corresponding smelting yield increased from 93.7 wt.% to 98.7 wt.% and the aluminum consumption decreased from 510 kg·t−1 to 400 kg·t−1. The multi-stage DG-ADP process enabled the internal circulation of vanadium-bearing materials in the ferrovanadium smelting system, as well as the external circulation of iron and residue slag in the same system, and finally achieved the zero discharge of solid and liquid waste from the ferrovanadium production line, which provides a brand-new perspective for the cleaner production of ferrovanadium alloy.

“…Основное отличие мембранной фильтрации от традиционных методов очистки, например, обычной объемной фильтрации, заключается в нанесении тонкого мелкопористого слоя на поверхность крупнопористого фильтра (получение мембраны). Поэтому подавляющая часть всех задержанных примесей скапливается не во всем объеме, а только на поверхности мембраны, образуя дополнительный фильтрующий слой осадка [4].…”
