摘要
辉钼矿(MoS_(2))是一种重要的含钼矿石,目前80%左右的钼来源于此类资源。工业上通常采用浮选-火法冶金工艺生产钼金属,然而该传统工艺易产生SO_(2)而造成环境污染,且存在回收率低、难以处理低品位矿石等问题。与之相比,湿法冶金因具备经济、环保、高效等优势而备受关注。为此,综合分析了近年来辉钼矿浸出技术的发展现状和前景,比较了不同钼分离提取方法的优缺点。通过分析指出,未来辉钼矿湿法冶金技术发展的核心在于浸出,利用开发新技术和优化条件实现高效钼浸出、通过缩短流程并实现工业化应用、提高伴生资源的同步回收等将成为重点研究方向。
Molybdenite(MoS_(2))is an important molybdenum-bearing ore.At present,about 80%of molybdenum comes from this kind of resources.In industry,flotation-pyrometallurgical process is usually used to produce molybdenum metal.However,this traditional process is easy to produce SO_(2)and cause environmental pollution,and there are some problems,such as low recovery rate,difficult to deal with low grade ore and so on.In contrast,hydrometallurgy has attracted much attention because of its advantages such as economy,environmental protection,high efficiency and so on.For this reason,the development and prospect of molybdate leaching technology in recent years are comprehensively analyzed,and the advantages and disadvantages of different molybdenum separation and extraction methods are compared.It is pointed out that leaching is the core of future development for molybdate hydrometallurgy technology.Developing new technologies and optimizing conditions to achieve efficient molybdenum leaching,shortening the process and achieving industrial application,and improving the synchronous recovery of associated resources will become the key research direction.
