The process used to treat sulfide copper ores begins at the mine site where the copper-bearing 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.
