新疆阿舍勒铜矿矿石工艺特征研究

新疆阿舍勒铜矿矿石性质复杂,矿物嵌布粒度细,矿石中除铜、硫外,尚伴生有锌、金、银、砷,这些元素均主要以独立矿物存在。通过矿石中主要元素的赋存状态及相关系数的研究,查明了Cu、Zn、Au、Ag、As的赋存规律,为矿石的开发利用指出了明确的方向。选矿试验证明,矿石中铜、锌的回收均获得了较理想的指标,由于砷的赋存状态和矿物晶体结构所决定,矿石中的砷在选铜的作业中将会在铜精矿中富集,目前用机械选矿方法仍无法进行铜、砷分离。

STUDY ON PROCESS MINERALOGICAL CHARACTERISTICS OF ORE FROM ASHELE COPPER MINE IN XINJIANG

The ore from Ashele copper mine in Xinjiang has a complex nature and fine size disseminationThere are accompanied zinc,gold,silver and arsenic existed in the ore as individual mineral but copper and sulfurThrough researching into the occurrence of main elements in the ore and the correlation coefficients,the occurrence law of Cu,Zn,Au,Ag and As is revealed and used for guidance of ore utilizationThe results of mineral processing experiments show that high recoveries of Cu and Zn are obtained Due to inherent occurrence of arsenic and crystal structures of minerals,arsenic in the ore will be enriched in copper concentrate in copper flotation operationAt present,the mechanical mineral processing is still impossible to separation of Cu from As
