浸蚀法是利用化学方法、原理在偏光显微镜下对金属矿物进行鉴定的重要辅助手段。本次运用一定浓度的KOH、HCl和HNO3等化学试剂对甘肃阳山金矿的常见金属矿物毒砂、黄铁矿、辉锑矿和方铅矿等进行浸蚀鉴定。研究结果表明：浸蚀法对硫化物、含硫盐及氧化物等具有明显的反应，能够有效区分物性特征相似的金属矿物，较好地显示矿物内部的微观结构，有助于快速鉴定物理特征相似的矿物，在研究矿石物化特性、形成环境以及矿床成因、指导找矿等方面发挥着重要的作用。

Etching method is an important supplementary means in metal mineral identification under polarizing microscope by using the method and principle of chemical.Using a certain concentration of KOH,HNO3 and HCl chemical reagent to identify the etching common metal mineral arsenopyrite,pyrite,stibnite and galena of the Yangshan gold deposit,researches show that this method works best for sulfide,salts contain sulfur and oxide and can effectively distinguish the similar physical characteristics of metal minerals.This method can show mineral internal microstructure bitterly and contribute to identify physical characteristics similar mineral quickly, play an important role in the study of physical and chemical characteristics,formation environments and ore genesis and guide the prospecting.
