New Insights into a Vanadium Precipitation Process by Hydrolysis Based on Manganese Salt Pretreatment.

Vanadium precipitation is the key step in producing vanadium products from vanadium solution. The sustainable development of the vanadium industry requires new environmentally friendly processes for vanadium precipitation. In this study, NaVO solution was pretreated with manganese salt to preliminarily separate the vanadium and sodium components.
