据苏州《有用矿物选矿》报道,苏联对使用含氯混合物浸出矿石中的贵金属进行了研究。确定了用几种混合物浸出金和银的最佳制度。最有前途的是氯化钠(150—300克/升)与次氯酸钙(2.5—5克/升)混合物。使用这种混合物在最佳浸出条件下,可使矿石中约90％的金和银转入溶液中。使用这种混合物,首先不需要使用毒性很大的氯,其次不需要在有专门设备的酸介质中进行浸出。 According to a report in Suzhou, “Beneficial Mineral Processing,” the Soviet Union conducted a study on the leaching of precious metals from ores using chlorine-containing compounds. The best system for leaching gold and silver with several mixtures was determined. The most promising are sodium chloride (150-300 g / L) and calcium hypochlorite (2.5-5 g / L) mixture. Using this mixture under optimal leaching conditions, about 90% of the gold and silver in the ore can be transferred into solution. The use of this mixture does not require the use of highly toxic chlorides in the first place and secondly does not require leaching in specially equipped acid media.
