摘　　要：锡铁山铅锌矿主要销售产品为铅精矿、锌精矿,伴生金属矿物金、银富集在铅精矿中计价,某一时期生产矿石中金回收率偏低,铅精矿中金元素含量低,影响了金元素计价,造成矿山生产经济损失。本文对该时期生产矿石类型进行统计,查明了金元素主要富集于大理岩型矿体中块状黄铁矿中,为难选型金矿石类型,从地质的角度解释了金元素回收率偏低的原因。The main selling products of Xitieshan Lead-Zinc Mine are lead concentrate and zinc concentrate. The associated metal minerals, gold and silver, are concentrated in lead concentrate for valuation,Causing economic losses in mine production. Based on the statistics of ore types produced during this period, it is found that gold element is mainly concentrated in massive pyrite in marble type ore body, which is a refractory type of gold ore.
