摘　　要：研究了从石煤灰渣中提取五氧化二钒的新工艺及最佳工艺条件。与钠化焙烧相比,减少了环境污染,提高了钒回收率,而且副产铵明矾,提高了经济效益。A new technology for recovering V205 from stone coal ash and the optimal technological conditions were described in this article. At the same time, the ammonia alum is obtained as a by-product. Compared with the sodium salt roasting, the environmental pollution is significantly alleviated as well as the vanadium recovery and economic benefit were obviously increased by use of the new technology.
