重选-浮选联合回收某硫化钼尾矿中氧化钼钨矿
Recovery of Tungsten and Molybdenum Oxides from a Molybdenum Sulfide Tailings by Gravity Concentration and Flotation
摘要
Abstract
The cost of bulk flotation for tungsten and molybdenum oxides from a molybdenum sulfide tailings is very high because of the existence of many carbonate minerals and clay minerals.In this paper, the process of gravity concentration-flotation was applied to recover the tungsten and molybdenum oxides from the molybdenum tailings.The results of the tests showed that tungsten and molybdenum bulk concentrate contained 18.92％ Mo with the recovery of 55.29％ and 26.79％ WO3 with the recovery of 62.51％ was obtained by a unite technology process, which included gravity concentration with Falcon centrifugal concentrator, the rough concentrate further treated with one stage of roughing, three stages of scavenging, one stage of pre-concentrating and another four stages of heating concentrating.This method provided a reference to the recovery of low-grade white tungsten ore and molybdenum oxide.关键词
