摘要
介绍了云南省锗矿资源开采回采率、选矿回收率和综合利用率“三率”调查研究结果。云南省锗矿工业类型以锗煤和含锗铅锌矿为主。开采方式均为地下开采,2018年保有资源储量35223.95 kt矿石,累计查明资源储量115618.53 kt矿石。含锗铅锌矿山开采回采率与锗煤型矿山接近,锗煤型矿山选矿回收率较高。目前锗矿综合利用率较低,含锗铅锌矿尾矿利用率高达100%。
The research results of the mining recovery rate,ore dressing recovery percentage and comprehensive utilization ratio of development and utilization of germanium ore in Yunnan is introduced.The industrial type of Yunnan germanium ore is focused on germanium coal and germanium-bearing lead-zinc ore,the mining way all is underground mining,the preserved resource reserve is 35223.95 kt ore in 2018,the cumulative detectable resource reserve is 115618.53 kt ore.The mining recovery rate of germaniumbearing lead-zinc mine is closed to germanium coal mine;the ore dressing recovery percentage of germanium coal mine is higher.The comprehensive utilization of germanium ore is low at present;the utilization rate of germanium-bearing lead-zinc tailings is up to 100%.
