本文描述了从碱性钢精炼渣中提取钒的方法。首先将渣和黄铁矿一起焙烧以中和渣中的氧化钙,可把焙砂磨碎,并用稀硫酸浸出。用三元胺溶剂萃取使浸出液进一步净化,从净化后的溶液中可沉淀出工业级的五氧化二钒。
This paper describes the extraction of vanadium from alkaline steel refining slag. The slag and pyrite are first roasted to neutralize the calcium oxide in the slag, which can be ground and extracted with dilute sulfuric acid. Extraction with triamine solvent further leachate purification from the purified solution precipitated industrial-grade vanadium pentoxide.
