金矿石提金金矿石提金extraction of gold from ore jinkuangshi tijin回收粗粒金最简单的方法是重力选矿，所用的设金矿石提金(extraetion of gold from ore)备有淘金盘、跳汰机、溜槽、摇床等。浮选法适于处理 以脉金矿石为原料生产金、银的金提取方法。主要有细粒金矿石。对于成分复杂的矿石，浮选法可以得到很氛化法提金、泥汞法提金、水溶液氛化法提金、硫脉法好的分选和富集效果。选得的金精矿根据其成分特点提金和徽生物提金。这些方法都属湿法冶金法，有时还用不同的冶金方法提金。铜金精矿、铅金精矿分别送需采用与选矿方法相结合的选冶联合法。铜、铅冶炼，随后从铜、铅阳极泥中提取金、银;金硫 无论采用哪种提金方法，都必须首先将金矿石破精矿则可直接用氛化法或焙烧一氰化提金。碎和细磨，使含金矿物(主要是自然金)全部或部分裸混汞法提金曾是重要的提金方法，因汞污染环境露。金颗粒越细，矿石也要磨得越细。如果金被裹在硫已很少使用。近代从金矿石或金精矿中提金的湿法冶化矿物(黄铁矿、毒砂)中，磨矿还不足以使金粒裸露金方法主要是氛化法。该法是使金矿石中的金溶解于时，就必须再经过焙烧、化学氧化、加压氧化或细菌氧有氧存在下的碱性氛化物溶液，然后再用锌粉(丝)将化等预处理来破坏这些硫化物矿，使之适于概化法处帆化物溶液中的金离子置换成金而沉淀析出。理。不经浮选而将全部矿石细磨后在强烈搅拌的槽中氛化浸出的方法称为全泥氰化。全泥氛化工艺有加活性炭从氛化矿浆中吸附金的炭浆法(CIP)、炭浸法(CIL)，有加离子交换树脂吸附金的树脂矿浆法(RIP)。现代大多数提金企业都按全泥氰化工艺流程组织生产。 帆化用设备是搅拌槽。对于小矿和贫矿(低品位)则用渗滤浸出和堆浸。 由于氛化物有剧毒，一直在寻求用非氛工艺来取代氰化法，如硫脉法、硫代硫酸盐法、水溶液氯化法和微生物法等，但这些方法尚处于试验研究阶段。
