     · After mixing with limestone the filtered concentrated ore is roasted in air or oxygen-enriched air on a moving belt. Most of the sulfide is converted to lead(II) oxide Sulfur dioxide gas can then be cleaned and used to make sulfuric acid. The lead(II) oxide is heated and made into lumps a process known as sintering.
