江城傜家山铜矿位于我省南部边缘,地处温热多雨的亚热带,矿石氧化较深,铜氧化率70～90%,矿区年降雨量在2200毫米左右,丰富的雨水大量带走经氧化淋蚀的铜,矿体上部有时仅留下铁帽,而淋滤带下部矿体中的脉石矿物几乎均含有铜.本矿属复杂砷酸型氧化矿,铜矿物有孔雀石、翠绿砷铜矿、橄榄铜矿、砷黝铜矿、羟砷铜矿、铜兰、光线铜矿、黑铜矿及少量次生硫化铜矿,其中硫化矿属氧化残余物,表面为氧化膜所复盖.脉石矿物以石英为主,高岭土次之,并含少量方解石、氢氧化铁、重晶石等.
Located in the southern edge of the province, Jiangcheng Qijiashan Copper Mine is located in a warm and rainy subtropical region. The ore is oxidized to a relatively deep extent with an oxidation rate of 70 to 90%. The annual rainfall in the mining area is about 2,200 mm. Eroded copper, the upper part of the ore body sometimes left only the iron cap, while the lower part of the leaching zone ore body gangue minerals contain almost copper. The mine is a complex arsenic-type oxide ore, copper minerals are malachite, green arsenic Copper ore, olive copper mine, arsenic tetrahedrite, hydroxyl arsenic copper mine, copper lantern, light copper mine, black copper mine and a small amount of secondary copper sulphide ore, sulphide ore belongs to oxidation residues, the surface is covered by oxide film The gangue minerals are mainly quartz, followed by kaolin, with a small amount of calcite, iron hydroxide, barite and so on.
