Metallurgical Content In metallurgy the operation of roasting as a preliminary to chlorination has for its object the expulsion of the sulphur arsenic antimony and other volatile substances existing in the ore and the oxidation of the metals left behind so as to leave nothing except metallic gold which can combine with chlorine when the ore is subsequently treated with it in aqueous solution
Roasting ore serves two purposes First it softens hard ores making them more easily broken or crushed which helps the melting process Secondly roasting reduces the sulfur content of ores which is harmful to the ironmaking process Roasting of ore can
