Abstract

The process of oxidizing-smelting roasting of vanadium-containing ferrophosphorus, which has a composition close to that obtained by joint melting of phosphorite agglomerate and vanadium quartzite, has been studied. It has been shown that vanadium is oxidized to V2O5 and forms a water-soluble compound Na VO3 with sodium in the course of oxidative roasting of a mixture of ferrophosphorus powder and Na2CO3 in a ratio of 10:1 at 800°C. After water-acid leaching of vanadium from the roasting cinder and precipitation of V2O5, a through extraction of vanadium into a commercial product of more than 75% is achieved.

The practical development of this technology will expand the raw material base of vanadium and create a new production of vanadium ferroalloys.
