Copper Roasting Diagram. C coppr pyrite decomposes into cuprous sulphide and ferrous sulphide. Casting and smelting of copper began around 4000 3500 bc.
Whether roast product is oxide or sulphate or partially sulphide would depend on temperature and partial pressures.

112 molten copper is fed into a moving mold involving parallel steel belts held in tension as the top and bottom of the mold.
Arseniates of iron copper lead when formed are not easily decomposed as they resist a high temperature and are only slowly converted into sulphates by sulphuric acid at a red heat. 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. Copper mostly occurs as sulfide ores which are heated in air to convert them to copperii oxide. Roasting arsenical pyrites feass.
