Copper Mining and Extraction: Sulfide Ores

From the formula, it is clear that iron and sulfur have to be removed in order to produce copper. The roasting process: changes some of the CuFeS 2 to copper oxide removes some of the sulfur as sulfur dioxide This is done by heating the concentrated ore from froth flotation. It is heated to between 500 °C and 700 °C in air.
