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.
