    copper processing

    Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products In its pure form or as an alloy, copper (Cu) is one of the most important metals in society The pure metal has a face-centred cubic crystal structure, andCopper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings Hydrogen peroxide was determined to be the best lixiviant Thus, copper and iron extractions were 634% and 486%, respectively, when leaching the slag with 3 M H 2 O 2, after 120 minutes of reaction at room temperature Copper dissolution was generally found to be the dominant.
