About 60 percent of the production of sulfuric acid is used to make phosphoric acid as part of the production process in making phosphate fertilizers and detergents. The steel industry is another user requiring large quantities. The acid is used for the removal of oxidation, rust and scale from steel sheets and billets as the final step in the steel making process. Other uses include nitrogen fertilizers and the “acid” in car batteries. One source of sulfuric acid is copper smelting. Most copper ores, especially those in North America are sulfate ores containing large amounts of sulfur. The smelting process releases sulfur dioxide gas, which is captured and turned into sulfuric acid. Strings of three to nine acid tank cars are common in trains.
