    Sulfur is mined from both surface and underground deposits, and is recovered as a byproduct from a number of industrial processes. In sulfur mining, three techniques are applied: conventional underground methods, conventional open pit methods, and the Frasch mining method. About 90% of all sulfur mined is obtained through Frasch mining.5

  1. Sulfur production in the United States

    Sulfur production in the United States was 9.04 million metric tons of sulfur content in 2014, all of it recovered as a byproduct, from oil refineries, natural gas processing plants, and metal smelters. The United States was second in the world in sulfur production in 2014, behind China. The sulfur recovered was marketed in the forms of native sulfur, and sulfuric acid. Total value was US$927 million in 2014. Byproduct sulfur from oil refineries, gas processing plants, and metal smelters is a "nondiscretionary byproduct," meaning that the sulfur recovery is mandated by environmental regulations put in place to prevent air pollution. Because the sulfur must be removed as a cost of producing the primary product, the sulfur byproduct will be sold, even at a price lower than the cost of recovery. This has enabled byproduct sulfur to drive other forms of sulfur production, notably Frasch sulfur, out of the market in the United States. Wikipedia
