Except for the controlled processes, less than ten percent of sulfur in coal may be fixed in coal ash due to the reaction of sulfur oxides with alkali components in coal. More sulfur may be retained in ash for some alkalirich young coals. The global emissions of sulfur oxides from human activities were around 90 Mt of sulfur per year in 1980.
