Extraction of Copper. Copper pyrites is the main ore. The method used to extract copper from its ores depends on the nature of the ore. Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores. The extraction

The reduction of zinc oxide to zinc occurs at a higher temperature than that required for the reduction of copper oxide to copper. Coke is used for the reduction of zinc oxide. Depending on whether sulphide or carbonate ores used for the extraction, the concentrated ore is either roasted or calcined.

leaching of high-grade copper oxide ore followed by EW of copper from the leach solution, produced low quality copper cathode at relatively high cost. In 1968 the tonnage of high-grade oxide ores was decreasing and vat leaching was on the decline. The second process, heap and dump leaching of low-grade oxide andor sulphide ore followed by ...

Extraction of copper from cuprous oxide copper I oxide Considering the Graph 1 the Cu 2 O line is at the top. So to reduce oxide ores of copper directly to the metal by heating with coke both the lines of C, CO and C, CO 2 are at much lower positions in the graph particularly after 500 600K. Most of the ores are sulphide and some may also contain iron.
