摘　　要：陕西王家坪原生金矿石是卡林型金矿,属于秦岭地区较典型的难处理金矿石,通过显微镜及电子探针分析手段对矿石中金矿物的赋存状态、嵌布粒度等进行了详细研究,同时对矿石物质组成,特别是对选冶工艺有害成分的矿物也进行了系统研究,目的是为选矿工艺设计提供依据。The primary gold ore in Wangjiaping, Shaanxi province is a Carlin-Type gold deposit which is the typical refractory gold ore in Qinling area. A study on occurrence,particle size and so on of gold minerals dissemi- nated in the ore was carried out with the help of mineralogical microscope and electronic probe. The mineral compo- nents,especially the compositions affecting recovering gold ,were also studied. The work aimed to provide basis for the design of mineral processing processes.
