甲玛铜多金属矿矽卡岩型矿石中硅灰石的综合利用

西藏甲玛铜多金属矿赋存着Cu、Mo、Pb、Zn、Au、Ag等多种金属组分,同时伴生硅灰石,资源储量十分丰富,但尚未综合利用,造成经济损失且污染环境。根据甲玛铜多金属矿矿石性质和选矿尾砂矿物组成的特点,可采用手选-筛选分离-浮选分离-超细粉碎工序从原矿和尾砂中综合回收硅灰石。研究结果认为,加强硅灰石的选矿试验、精选分级、实际应用研究,充分利用资源优势,开发生产技术含量和附加值高的新产品,将为企业创造良好的经济效益和社会效益。本文就该矿床硅灰石的地质特征,硅灰石综合利用产生的效益、市场需求,可选性论证及大致流程等方面进行初步探讨,并提出了硅灰石综合利用建议。

The Comprehensive Utilization of Wollastonite in Skarn Type Ore of Jiama Copper Polymetallic Deposit in Tibet

Many polymetallic components such as Cu、Mo、Pb、Zn、Au、Ag exist in the Jiama copper polymetallic ore in Tibet.At the same time the resources reserves of wollastonite are abundant,but it cannot be used synthetically,causing the economical loss and environmental pollution.According to the ore properties of the Jiama copper polymetallic ore and characteristics of mineral compositions of the tailings,the flowsheet of hand-sorting separation-screening separating-flotation separation-ultrafine grinding was adopted for comprehensive recovery of wollastonite from the raw ore and tailings.According to the study it is believed that great economic and social benefit would be achieved by beneficiation tests,and degrading and practical application research to make full use of the advantage of mineral resources and develop products with high technological content and added value.The geologic character of wollasonite,the benefit,demand of market,the optional argument,the process and other aspects are roughly discussed in this paper.Also,some suggestions were offered for the comprehensive utilization of wollasonite.
