Copper Mining And Extraction Oxide Ores

The process used to treat sulfide copper ores begins at the mine site where the copperbearing minerals are physically separated from the rest of the rock the flow diagram below shows how the percentage of copper increases as the ore is refined first physically by froth flotation then chemically by smelting and finally electrolytic refining

Copper Extraction From Sulfide Ores Latest Contents

This process is used for the extraction of copper from low grade sulfide ore in this process the crushed and ground ore in bulk about 100000 tons is exposed to air and water in big tanks the air in the presence of water gradually oxidizes copper and iron sulphides to their surphides the process is completed in about one year
