从彩钼铅矿中提取钼的研究现状

Research Status of Molybdenum Extraction from Wulfenite

彩钼铅矿是一种具有高工业价值的含钼矿物,因所含杂质元素不同而呈黄、鲜红、橄榄绿或浅灰等颜色,其主要成分是钼酸铅,属于离子型化合物,可溶于许多酸、碱和盐,有较好的浸出效果。本文概述了彩钼铅矿的几种分离提取方法,包括化学浸出工艺和生物浸出工艺,对比阐述了各个工艺技术的特点与优劣,并对未来彩钼铅矿中钼和铅的绿色高效提取新技术进行了展望。

Wulfenite is a kind of molybdenum-containing mineral with high industrial value,which is yellow,bright red,olive green or light gray due to different impurity elements.Its main component is an ionic compound of lead molybdate,which is soluble in many acids,alkalis and salts with good leaching effect.The characteristics of several extractions processes including chemical leaching and biological leaching from wulfenite have been summarized in this paper,as well as the pros and cons of each above process technology.And the green and efficient extraction technology for molybdenum and lead from wulfenite is prospected.
