摘要

张家沟银矿位于华北克拉通北缘,是一个近期取得较大找矿突破的中型银矿床,隶属少郎河多金属成矿带。矿床类型为产于蚀变破碎带中的脉型银矿床。矿石银矿物以辉银矿为主,其次为银黝铜矿、锌砷黝铜矿和自然银。黄铁矿中的辉银矿不易选,占58.57%,方铅矿、闪锌矿中的辉银矿易选,占22.28%,总体显示不易选的特点,选矿流程要和其他伴生组分综合考虑。

Abstract

Zhangjiagou silver deposit is located in the northern margin of North China Craton,and has been a medium-sized deposit resulted from the breakthrough in exploration in latest years,and becomes a significant member of Shaolanghe metallogenic belt.In this contribution,the geology and occurrence modes of silver minerals in ores are discussed.The silver minerals in ores are mainly argentite,secondly freibergite,zinc-tennantite and native silver.The 58.57% of argentite is in pyrite and difficult for dressing,whereas the 22.28% of argentite in galena and sphalerite is much facilitated to separate.In general,the gold ore is refractory ore,it should take other associated elements into account in the flowsheet of ore processing.
