Get PriceRefining with Sulphur A more speedy method of removing iron, copper, lead and base metals from bullion is to add sulphur to the molten metals. Although gold sulphides may be readily formed in the wet way, they are decomposed into gold and sulphur by merely heating them to a temperature below 300 deg. C. If pure gold is heated strongly with sulphur no combination of the elements appears to take ...
