for sulfuric acid production, sulfur production from pyrites was about the same. Since 2005, between 81% and 83% of the world's sulfur production as elemental sulfur and byproduct sulfuric acid came from recovered sources. Some sources of sulfur were unspecified, which means that the material could have been, and likely was, elemental sulfur or byproduct sulfuric acid.
