In the copper smelting business the main ore that is processed is CuS. The ore is crushed to a fine powder and the CuS separated by floatation. The finely divided CuS is then placed in a crucible ( assume it is adiabatic) and air is blown through it. This converts the CuS to CuO. The CuO is then transferred as a melt to a second crucible and propane is blown through it.
a) What amount of heat, per ton of CuS, is required to melt the CuO in the first crucible?
b) What are the products of the second reaction and what is AG for the reaction? c) What are the by products of the airl CuS reaction and what are the
environmental implications (support your answer with chemical equations).
