Zinc - Essential Chemical Industry

However, any iron sulfide present in the ore will be converted to iron(III) oxide, which reacts with zinc oxide to form zinc ferrite: In the simple leaching process, this zinc cannot be easily recovered and so ores with low iron content are preferable. The sulfur dioxide is often converted to sulfuric acid in a plant adjacent to the smelter.
