摘　　要：闪锌矿是目前工业上提炼Cd的最主要载体矿物,我省锌探明金属量达5.851 4×10^(6)t,伴生Cd的资源量潜力巨大。本次选取长山-双井铅锌矿床作为研究对象,在地质观察和电子探针分析基础上,划分了四个世代闪锌矿矿石,计算出伴生Cd预测资源量分别为213.51 t、270.00 t、197.28 t、33.59 t。对比勘探报告显示,本文计算出长山-双井矿床闪锌矿Cd的资源量合理可信,可为矿床后续开采过程中Cd的综合利用提供依据,为我省铅锌矿床伴生Cd的利用和资源量估算提供借鉴。At present,sphalerite is the most important carrier mineral for cadmium extraction in industry.The proved metal amount of zinc in Anhui Province is 5.8514×10^(6)t,with huge resource of associated cadmium.This study focuses on the Changshan-Shuangjing lead-zinc deposit,for which four generations of sphalerite ores were divided by geological observation and electron probe micro analysis,and the calculated associated cadmium resources were 213.51 t,270.00 t,197.28 t and 33.59 t,respectively.Compared with the exploration report,the calculated results are reasonable and reliable,which can provide a basis for comprehensive utilization of cadmium in the subsequent mining process of the deposit,and provide a reference for the utilization and resource estimation of associated cadmium in the lead-zinc deposits in the province.
