新桥硫铁矿伴生金银赋存状态及分布规律

新桥硫铁矿是一大型多金属硫化物矿床 ,矿石的主要化学成分有铜、硫、铁、铅、锌 ,并伴生有以金、银、镉为主的 13种有益组分 ,其中金矿物以自然金为主 ,大部分呈细粒分散状包裹嵌布于磁黄铁矿和黄铜矿中。银矿物主要为自然银、银金矿 ,亦呈细粒分散状包裹嵌布于脉石、磁铁矿和黄铜矿中。金银在矿床中分布不均 ,在矿体走向和向深部方向局布富集有一定规律。有必要进一步圈定金、银异常区 ,进行独立金、银矿体找矿和资源预测。本矿金、银皆属难解离型 ,建议在电解粗铜中综合回收利用

PRSERVATIVE STATE AND DISTRIBUTIVE LAW OF GOLD AND SILVER ASSOCIATED IN XlNQIAO PYRITE

Xinqiao pyrite is a large polymetal sulfide deposit.Its main Chemical compositions included copper,sulfur,iron,lead,zine,and associated with 13 kinds of profitable components primarily as gold,silver and cadmiun,among the gold minerals prymarily as natural gold,and most of it distributed set in magnetic pyrite and chalcopyrite,present thin particle dispersive enclave in form.Silver minerals primarily as natural silver and electrum,and also distributed set in veinstone,magnetite and chalcopyrite,present thin particle dispersive enclave in form,Distribution of gold and silver in the ore deposition appears unbalance,and there are certain law to enrich locally along the strike of ore body and deepen direction,so ought to further defined abnormal area of gold and silver,carry out search and prediction of single gold and silver ore bodys.Gold and silver of this ore are all difficult to separate,so suggest pay attention to comprehensive recover and utilization in electrolysis of blister copper.
