摘要

PPROBLEM TO BE SOLVED: To provide an effective method for efficiently recovering copper from a copper-containing substance (particularly copper from a copper sulfide such as chalcopyrite and chalcocite), which realizes a high copper recovery rate at a reduced cost compared to conventional treatment techniques. PSOLUTION: The method for recovering copper and other metal values from a metal-containing material generally utilizes ultrafinely grinding and medium temperature (140-180C) pressure leaching technique, wherein ultrafine ground powders are controlled to reduce its grain size to 25 m. The method of the present invention is beneficial for recovering metals (e.g. copper, gold, silver, nickel, cobalt, molybdenum, rhenium, zinc, uranium and platinum-group metals) from metal-bearing materials, and shows a particular utility in connection with the extraction of copper from copper sulfide ores and concentrates.

要解决的问题：提供一种有效地从含铜物质（尤其是从黄铜矿和黄铜矿等硫化铜中回收铜）中回收铜的有效方法，与降低成本相比，该方法可实现较高的铜回收率。常规治疗技术。

解决方案：从含金属的材料中回收铜和其他金属价值的方法通常利用超细研磨和中温（140-180C）压力浸出技术，其中将超细磨粉控制为将其粒度减小至<25米本发明的方法对于从含金属的材料中回收金属（例如铜，金，银，镍，钴，钼，rh，锌，铀和铂族金属）是有益的，并且在与从硫化铜矿石和精矿中提取铜。
