Gold Processing Methods Iron Slag

Jan 18 2017 The iron in the gold ore can be removed by the oxidation of the iron by use of either a forced air oven or nitric acid. The iron oxide may then be removed from the gold materials to be smelted and thus reducing the problems that may be caused by their oxidation inside the smelter. 3.
