某多金属矿岩矿采样与化验鉴定研究

Research on Sampling,Analysis,and Identification of Rock and Mineral Resources in a Certain Polymetallic Mine

山东省某多金属矿矿产资源丰富,矿床中成矿金属元素含量丰富。为明确岩矿中相关金属元素含量,通过矿物的光、声、硬度及主要的化学成分特征进行化验分析,完成岩矿鉴定。实验结果表明:各样品Ⅰ级标准物质的各元素分析结果均符合监控要求,230个监控样品结果符合规范要求,内检分析合格率符合规范要求,异常抽查分析合格率也符合规范要求。

A certain polymetallic deposit in Shandong Province is rich in mineral resources,and the content of ore-forming metal elements in the deposit is abundant.To clarify the content of relevant metal elements in rocks and minerals,laboratory analysis is conducted through the light,sound,hardness,and main chemical composition characteristics of minerals to complete rock and mineral identification.The experimental results show that the analysis results of each element in the Class I standard substance of each sample meet the monitoring requirements,and the results of 230 monitoring samples meet the regulatory requirements.The qualification rate of internal inspection analysis meets the regulatory requirements,and the qualification rate of abnormal sampling analysis also meets the regulatory requirements.
