Roasting Of Copper Pyrites

2018-3-19Pyrites roasting is important because of sufates. Since it is hard to change a sulfate salt a salt is any metal and acid to a halogen because SO4 is at the bottom of the list the only way I know how to discribe it heating to high temperature needed to break the sulfate bond sulfuric doesnt boil SO2 at low temperature 700 degress F would be my minimum goal in air for about an hour.
