武警黄金十支队试验成功“无污染封闭水溶溶样提纯法”,以提炼砂金中的金、银。该法较好地解决了原“王水加热溶解法”存在的工艺复杂、设备腐蚀、环境污染等问题,成本降低80%,而金、银的纯度可分别提高到99%及30%以上,回收率可超过95%,且具有不损坏溶样设备、不污染环境等优点。 Gold Brigade 10 successful trial of the “non-polluting water-soluble dissolved sample purification method” to extract the gold in gold, silver. The method solves the problems of complex process, equipment corrosion and environmental pollution existing in the original “aqua regia heating and dissolving method”, the cost is reduced by 80%, while the purity of gold and silver can be increased to 99% and 30% respectively, The recovery rate can exceed 95%, and has the advantage of not damaging the sample-dissolving equipment and not polluting the environment.
