本发明是关于从含银和可能含金的固体物料中回收金银的方法,该二种金属在物料中品位很低,一部分呈游离硫化物状,可能与元素硫混杂在一起。本方法尤其适用于回收锌浸出渣浮选固体精矿中的金银。锌矿浸出渣一般含有银、金、硫、硫酸铅和少(旦力)的杂质。利用各 The present invention relates to a method for recovering gold and silver from a silver-containing and possibly gold-containing solid material which is low-grade in the material and partially free sulfides, possibly mixed with elemental sulfur. This method is especially suitable for the recovery of gold and silver in flotation solid concentrates of zinc leach residue. Zinc ore leach residue generally contains silver, gold, sulfur, lead sulfate and less (denier) impurities. Use each
