摘要
介绍了国内外含钼废催化剂中钼的回收技术。全文对比了传统干法、湿法的技术现状,重点分析了湿法中酸浸、碱浸、水浸等工艺的优缺点,以及超声辅助法、微波辅助法等新方法的研究进展。下一步的技术研究需要努力实现低环境负荷、高经济效益,同时加强与其他金属的共同分离提取。
Several recycling methods for molybdenum from spent catalyst were particularly described.Advantage and disadvantage of these traditional methods of dry metallurgy and hydrometallurgy were contrasted in a list , followed with new methods such as ultrasound assisted leaching and microwave assisted leaching , while acid leaching and alkaline leaching were focused on.The next step of the research was to reduce the environmental load of recycling methods and get high economic benefit , separation of molybdenum and other metals still need further studies.
