银洞坡金银矿是一个较复杂的含炭质金银多金属硫化矿,我们采用无氰浮选工艺流程,综合回收了金、银、铅、锌、硫及镉等六种元素。一、矿石性质矿石中金属矿物以黄铁矿、方铅矿及闪锌矿为主,其次有少量的黄铜矿及褐铁矿等。金银矿物以自然金、银金矿及金银矿为主,其次有银金齐、自然银、针碲金银矿、辉银矿、辉铜银矿、硫铜银矿、硫锑银矿及硫砷银矿等。脉石矿物以石英、长石及绢云母为主,其次还有少量炭质。黄铁矿、方铅矿及闪锌矿的嵌布粒度较粗,一般粒径为0.1～1.0毫米。黄铜矿以细粒嵌布为主,其中小于0.075毫米者占45％,主要呈乳滴状嵌布在闪锌矿及其他金属硫
Silver Dongpo gold and silver mine is a more complex carbonaceous gold, silver and polymetallic sulfide ore, we use non-cyanide flotation process, a comprehensive recovery of gold, silver, lead, zinc, sulfur and cadmium six kinds of elements. First, the nature of ore Ore in mineral pyrite, galena and sphalerite, followed by a small amount of chalcopyrite and limonite. Gold and silver minerals are mainly natural gold, silver and gold and gold and silver ore, followed by silver gold, natural silver, silver tellurium gold, silver, silver glitter, silver copper sulfide, silver sulfide, antimony silver And sulfur arsenic silver and so on. Gangue minerals quartz, feldspar and sericite-based, followed by a small amount of carbonaceous. Pyrite, galena and sphalerite embedded coarse cloth size, the general size of 0.1 to 1.0 mm. Chalcopyrite to fine-grained cloth, of which less than 0.075 mm accounted for 45%, mainly in the droplet embedded in the sphalerite and other metal sulfur
