摘要：
The invention relates to a method for recovering the valuable metals from sulphidic raw material containing at least copper and zinc by means of hydrometallurgical treatment. Copper sulphide and zinc sulphide are components of the raw material, and are leached by means of an alkali chloride- copper (II) chloride solution. The divalent copper chloride is removed from the solution that is formed, and the solution is routed to zinc extraction to remove the zinc from the alkali chloride-copper chloride solution. The solution exiting zinc extraction, which is depleted with regard to zinc, is routed to final solution purification and copper recovery. The reagents required in the process are obtained primarily as products of the chlorine-alkali electrolysis that is related to the process.
摘要（中）：
本发明涉及通过湿法冶金处理从至少含有铜和锌的硫化物原料中回收有价金属的方法。 硫化铜和硫化锌是原料的组分，并通过氯化亚铜 - 氯化铜（II）溶液浸出。 从形成的溶液中除去二价氯化铜，将溶液送至锌提取，以从碱金属氯化物 - 氯化铜溶液中除去锌。 离开锌提取物的溶液，其被用于锌，被耗尽到最终的溶液纯化和铜回收。 该方法中所需的试剂主要作为与该方法有关的氯 - 碱电解产物得到。
