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. Our main products include crushing equipment, sand making equipment, beneficiation equipment, grinding equipment and building materials equipment, welcome to purchase;
