一、概述矿石中主要金属矿物有黄铁矿、黄铜矿和闪锌矿;主要脉石矿物有石英、绿泥石、白云母、透闪石及方解石。黄铁矿一般颗粒0.282毫米,最小为0.096毫米;黄铜矿一般颗粒0.064毫米,最小为0.0064毫米;闪锌矿一般颗粒0.024毫米,最小为0.0013毫米。形成相互串插,包裹的浸染状及网状等结构,属难选矿石。原工艺系一次细磨后按 First, an overview The main minerals in the ore are pyrite, chalcopyrite and sphalerite; the main gangue minerals are quartz, chlorite, muscovite, tremolite and calcite. Pyrite general grain 0.282 mm, a minimum of 0.096 mm; chalcopyrite particles 0.064 mm, a minimum of 0.0064 mm; sphalerite general 0.024 mm particles, a minimum of 0.0013 mm. The formation of mutual stringing, wrapped disseminated and reticular and other structures, is refractory ore. The original process after a fine grinding press
