铅锌矿石中的银,储量占30%左右,产量占45%以上,为银的重要来源。近年来,由于银价上涨,国内外均重视改善银的回收工艺问题。目前,国内铅锌矿石中银的选矿回收率在45—82%之间,国外水平略高。在选矿过程中,进入铜精矿和铅精矿中的银,可在冶炼过程中回收。进入锌精矿的银只有少数几个冶炼厂回收,但计价只有铅精矿中银的三分之一。我国南钢引进的日本光和法,展现了黄铁矿烧渣提银的前景,但该方法要求 Silver in lead-zinc ore reserves of about 30%, accounting for more than 45% of the output, an important source of silver. In recent years, due to the rising price of silver, both domestic and foreign countries attach importance to improving the silver recycling process. At present, the domestic ore recovery rate of lead-zinc ore in the silver between 45-82%, slightly higher level of foreign countries. In the beneficiation process, silver entering the copper concentrates and lead concentrates can be recovered during the smelting process. Silver entering the zinc concentrates is recovered by only a few smelters but is priced at only one-third of the silver in lead concentrates. China’s Nangang introduced Japan’s light and law, showing the prospect of pyrite cinder mention of silver, but the method requires
