  • 黔东南天柱—锦屏地区金矿石质量评定方法探讨……程元路
  • 摘 要:黔东南地区金矿石多以明金为主,单颗粒明金可达中—粗粒级,品位变化大,利用传统的采样方法、样品加工流程和矿石分析方法难以获得准确的结果,导致影响对矿石质量的评估、工业矿体的圈定和储量计算,以及矿石开采和选冶等。以黔东南天柱—锦屏地区金矿石为例,分析了矿石测定不准确的原因,通过实验确定合适的样品取样量、分析方法,可获得准确的测定结果,为进一步研究该类型金矿床的成矿规律,客观评估本区金矿经济效益提供参考。

    Review onthe quality assessment method for gold-containing ores in Tianzhu-Jinpingarea,southeastern Guizhou……Cheng Yuanlu

    AbstractThe ores in southeastern Guizhou are mostly visiblegold.Single grain visible gold can reach medium-coarse grain size.Themineralization is extremely uneven so that conventional sampling method,sampleprocessing flow sheet and ore analysis method can not obtain accurateresults,making it difficult for ore quality assessment,industrial ore bodydelineation,reserve calculation and the extraction and beneficiation ofores.The paper conducted a case study of the ores from Tianzhu-Jinping area insoutheastern Guizhou,analyzed the cause of inaccurate determinationresults,determined reasonable sampling weight and analysis method throughtests,and thus accurate results were obtained,which provide reference tofurther study the ore-formingrules of the type of ores and rationally assess the economic benefits in thearea.
