观山铜矿系多金属矿山。生产铜、铅、锌三种精矿产品。近几年在含硫5％左右的尾矿中综合回收硫铁矿,取得了较好的技术经济指标。 (一)矿石性质观山铜矿属多金属低品位硫化矿。金属矿物以黄铜矿、方铅矿为主,闪锌矿次之(随地质资源变化锌逐渐消失),还有黄铁矿、菱铁矿、重晶石等。矿石含铜0.3—0.5％,铅0.7—
Guanshan copper mine polymetallic mines. Production of copper, lead, zinc three kinds of concentrate products. In recent years, about 5% sulfur tailings in the comprehensive recovery of pyrite, and achieved good technical and economic indicators. (A) the nature of ore Guanshan copper mine is a multi-metal low-grade sulfide ore. Metallic minerals are mainly chalcopyrite and galena, followed by sphalerite (gradually disappearing with changes in geological resources), as well as pyrite, siderite and barite. Ore copper 0.3-0.5%, lead 0.7-
