摘要
江西某铜钼钨矿矿石中有用矿物以黄铜矿、辉钼矿、黑钨矿为主,并伴生有磁黄铁矿.为了给该矿产资源的开发利用提供依据,对其进行了选矿试验研究.经试验比较,采用铜钼混浮-铜钼分离-尾矿脱硫-重选回收黑钨矿的联合工艺流程.获得了比较理想的铜精矿、钼精矿、钨精矿3种精矿产品,铜精矿品位为26.38%,回收率为91.35%;钼精矿品位为51.23%,回收率为83.54%;钨精矿品位为52.58%,回收率为65.49%.使矿石中的有价元素得到了较好的综合回收.
A copper-tungsten-molybdenum ore from Jiangxi contains mainly chalcopyrite 、molybednite and wolframite as valuableminerals that are associated with magnetic pyrite.Beneficiation tests were made on this ore to provide a basis for its exploitation andutilization.Analyses the dressing experiment research.Test by comparison,The first,using Cu-Mo mixing floatation,Then,Cu-Mo separation,last ,wolframite recovery by gravity separation .Which obtained copper concentrate grading 91.35 % at a recovery of 26.38 %;molybdenum concentrate grading 83.54 % at a recovery of 51.23 %;tungsten concentrate grading 71.25 % at a recovery of 52.58 %.Achieving a good comprehensive recovery of the valuable elements of the ore.
