Method of enriching and recovering vanadium resource in vanadium slag

The invention discloses a method of enriching and recovering a vanadium resource in vanadium slag and belongs to the metallurgical technical field. The method comprises the following steps of proportioning a slag modifying agent, an iron-containing material and a reducer in proportion into vanadium-enriched vanadium slag powder; and carrying out smelting reduction and slag and metal separation onthe vanadium-enriched vanadium slag powder and the iron-containing material under the action of high temperature and the reducer to obtain a vanadium-enriched ferroalloy. The method is short in process flow, simple in process and high in vanadium recovery rate in full flow and can recover the vanadium source in the vanadium slag fully. The flow is free of waste acids and waste water, and is relatively small in environmental pollution and green and environmental-friendly. 本发明公开了一种富集回收富钒渣中钒资源的方法，属于冶金技术领域，包括：使富钒渣粉料配加与之成所定的比例的炉渣改质剂、含铁物料和还原剂，并在高温及还原剂作用下使富钒渣粉料和含铁物料进行熔化还原、渣金分离得富钒铁合金。本发明工艺流程短，工艺简单，全流程钒回收率高，能够充分回收富钒渣中的钒资源；且本流程
