辽宁省凤城市高砷金矿矿石工艺矿物学研究

Study on technological mineralogy of high arsenical gold ores of Fengcheng County,Liaoning Province

研究辽宁省凤城市三个金矿矿粉的工艺矿物学的目的，是为了细菌预氧化—氰化提金工艺研究提供主要参考依据。其研究重点是查明金在矿粉中的赋存状态、嵌布粒度、形态、成色等工艺特性，对矿粉中金矿物的解离状态进行考查。同时，对矿粉的物质组成及具有综合回收价值的银也进行了研究。

The aim of studying technological mineralogy of gold ore powder of the gold deposits in Fengcheng County of Liaoning Province is to provide main reference basis for the study of the technology of bacterial oxidation cyaniding.The emphasis of the study is placed on the ascertainment of technological features as gold occurrence in ore powder,disseminated state,shape,fineness etc as well as on the investigation of the dissociated state of the gold mineralin ore powder.In addition,the composition of ore powder and thesilver minerals in it which possess great value to be synthetically recovered are studied also.
