Ammonia Leaching A New Approach of Copper Industry in How Hydrometallurgy and the SX/EW Process Made Copper the

Dec 10 32 The investigations in this field indicate more frequent use of this method for extracting copper from ore and concentrate relative to other basic metals In this paper an attempt was made to describe the basis and different ammonia leaching methods and present the major research activities in this field for copperOxidised copper ore bodies may be treated via several processes with hydrometallurgical processes used to treat oxide ores dominated by copper carbonate minerals such as azurite and malachite and other soluble minerals such as silicates like chrysocolla or sulfates such as atacamite and so on

Copper Concentrates Cargo Handbook the world s largest The cuprex metal extraction process Recovering copper

The process of liberation of copper ores depends upon whether they are oxide or sulfide or Subsequent steps depend on the nature of the ore containing the copper For oxide ores a hydrometallurgical liberation process is normally undertaken which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plantThe Cuprex metal extraction process produces cathode grade copper using a hydrometallurgical process based on chloride leaching of sulfide ore concentrat The process incorporates several novel
