摘要
东湾金矿是构造蚀变岩型金矿床。运用光谱、化学分析及光片、薄片鉴定等研究手段发现,东湾金矿床矿石为少硫化物金矿石;金矿物主要为自然金,其次为银金矿;金主要以可见金和不可见金两种状态存在。可见金主要为细粒金、微细粒金,一般呈包裹金产出,包裹于黄铁矿中,少量为裂隙金、粒间金。自然金呈它形粒状,以角粒状为主。以上研究结果为本区矿石加工、选冶提供了重要参考资料。
Dongwan gold mine is a gold deposit of tectonic altered rock.DongWangold mineral be considered little sulfides gold ore by these research measure,such as spectrum,chemical analysis尧appraisal of light-strip and slice,Gold ore primary is nature-gold ore,secondly is sliver-gold ore.The gold has two type both visible gold and onsubmicro-gold.It can be seen gold has fine particle and micro-fine particle,it majority involved is inclusion gold,be included by pyrite,so fissure-gold and included-gold is few.Gold natural form be presented shape of xenomorphic granular and angular grainy.This studying in order to provide reference in mining area such as ore processing尧flotation-metallurgical process.
