摘要
九华山铜矿床中伴生金已具综合利用价值。金以矿物态为主，金矿物主要为银金矿、含银自然金。金矿物粒度较细，大于２００目者占２４．３４％，金矿物主要嵌布于黄铜矿粒间或裂隙中。金的理想回收率为６６．３０％，空间分布上，沿矿体走向金西低东高，倾向金北高南低，深度金随深度增加而增加。
The associated gold in Jiuhuashan copper deposit is significant for comprehensive utilization.Gold mainly exists as gold minerals,including electrum,silver-bearing native gold.The grain size of gold minerals is relatively fine with only 24.34% being greater than 200 mesh.Gold minerals occur mainly in the micro-cracks of chalcopyrite or along the boundries of chalcopyrite grains.The ideal recovery of gold is 66.30%,Spatially,gold grade appears to be higher in the east and lower in the west along the strike of the orebodies,and to be higher in the north and lower in the south along the dip of the orebodies,and tends to increase with the depth.
