摘　　要：对某斑岩型金矿进行工艺矿物学研究,查明其化学成分、结构构造、矿物组成、目的矿物的嵌布粒度以及金的赋存状态等工艺矿物学特征。结果表明:矿石中金的品位为2.81*10^(-6),金主要赋存于银金矿中,银金矿含金75.95%,含银22.98%。银金矿多数粒度较粗,可采用重选法对银金矿进行回收。The process mineralogy of one porphyry type gold ore was carried out to find out its chemical component,structure construction,mineral composition,and dissemination size of the target mineral,as well as the occurrence state and other process mineralogy features of gold.Results show that:the gold grade of the ore is 2.81*10^(-6),gold mainly occurs in silver-gold mines,in which gold content is 75.95%,and silver content is 22.98%.Most of the silver-gold ore has coarse granularity,so gravity separation can be adopted for the recovery of silver-gold ore.
