Abstract

Abstract

Based on the process for production of high purity vanadium pentoxide from low grade vanadium slag, a systematic research was carried out for improving the vanadium recovery rate, the grade of ammonium polyvanadate and vanadium pentoxide, and decreasing the material and energy consumption as well as the product impurities simultaneously. The conversion rate more than 86% for the vanadium slag, the grade more than 89.5% and 99% respectively for ammonium polyvanadate and vanadium pentoxide can be obtained finally. The content of impurities and high density metal inclusions in products can meet the requirements of the customers such as Kennametal and Reading titanium alloy companies.
- high-purity vanadium pentoxide,
- vanadium slag,
- ammonium polyvanadate,
- low impurity
