钼尾矿中有价金属的综合回收研究现状

随着钼产业的快速发展,大量钼尾矿逐年堆积,对自然生态环境造成了严重的污染.钼尾矿因原矿矿石性质、所用工艺等差异呈现不同的特性,但均含有钼、钨、铁等多种有价成分,是一种可利用的二次矿产资源.从钼尾矿中回收共伴生的有价金属是综合利用的一个关键环节.本文综合评述了钼尾矿的资源特点,并详细地总结了近年来回收共伴生有价金属的生产工艺、研究现状及进展,涉及钼、钨、铜、铁、硫等元素的综合回收,也对钼尾矿资源综合利用存在的一些问题进行了探讨,同时提出了合理化建议.

Review of comprehensive recovery of valuable metals from molybdenum

With the rapid development of molybdenum industry, a large number of molybdenum tailings has being accumulated year by year, which caused serious pollution to the natural ecological environment. Molybdenum tailings have different characteristics due to the differences in the properties of raw ore and the technology used, but they all more or less contain a variety of valuable components such as molybdenum, tungsten and iron, and are typical secondary resources that can be used. The recovery of co-associated valuable metals from molybdenum tailings is a key link in comprehensive utilization. In this paper, the resource characteristics of molybdenum tailings and the production process, research status and progress of the comprehensive recovery of co-associated valuable metals are reviewed in detail, involving the comprehensive recovery of molybdenum, tungsten, copper, iron, sulfur and other elements. Mealwhile, some problems of molybdenum tailings resources comprehensive utilization are also discussed, and rationalization proposal are given in this paper.
