Copper Mining and Processing Processing Copper OresA. Processing of Oxide OreB. Processing of Sulfide OreC. Recycling CopperOxide ores are generally processed using hydrometallurgy. This process uses aqueous (waterbased) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps heap leaching, solvent extraction, and electrowinning. Heap Leachingis the process of using percolating chemical solutions to leach out metals. Heap leaching is very commonly used for lowgrade ore, which would otherwise not be economical to send through a milling process. Following mining, tranFrom Ore to Finished Product CopperProcessing of Copper Ore The first step in processing the ore removed from the mine is
27/9/2019· Since the introduction of hydrometallurgical process for copper in the late 1980s, it has been widely used in China, especially for copperbearing materials that cannot be effectively recovered by conventional processing methods, such as waste rock from openpit ore stripping and lowgrade copper oxide ore. Hydrometallurgical process is the

The process. The concentrated ore is heated strongly with silicon dioxide (silica), calcium carbonate and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulphide (which is reduced further to copper metal in the final stage).

6/7/· With the gradual decrease in the grade of copper ores being processed, copper concentrates have become more complex with higher impurity and gangue content. This trend has had a detrimental effect on smelters as they have to increase throughput to maintain copper metal production, while increasing operating costs due to processing the increased amounts of secondary products
