The important sulfur cycle is a biogeochemical cycle in which the sulfur moves between rocks, waterways and living systems. It is important in geology as it affects many minerals and in life because sulfur is an essential element (), being a constituent of many proteins and cofactors, and sulfur compounds can be used as oxidants or reductants in microbial respiration.

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 (83 percent), natural gas processing plants (10 percent), and metal smelters (7 percent). The United States was second in the world in sulfur production in 2014, behind China.
The vast majority of the 64,000,000 tonnes of sulfur produced worldwide in 2005 was byproduct sulfur from refineries and other hydrocarbon processing plants. [3] [4] [5] Sulfur is used for manufacturing sulfuric acid, medicine, cosmetics, fertilizers and rubber products. Elemental sulfur is used as fertilizer and pesticide.
The Gulf Coast came to dominate world sulfur production in the early and middle 20th century. [7] However, starting in the 1970s, byproduct sulfur recovery from oil and natural gas lowered the price of sulfur and drove many Frasch-process mines out of business. The last United States Frasch sulfur mine closed in 2000. [8]

Nevertheless, extracting the sulfur created serious ecological hardship on the country. [7] By 1912 the United States overtook Sicily for the worldwide production of sulfur. Large consistent bases of sulfur in Texas and Louisiana, as well as low-cost fuel and large quantities of water, made the newly invented Frasch process economical. [5]
At this time, all participants are in a listen-only mode. ... So, there is about 600,000 tons in 2025 that we would like to sell into that export market for our high-sulfur production. But if it's ...
The lead chamber process was an industrial method used to produce sulfuric acid in large quantities. It has been largely supplanted by the contact process.. In 1746 in Birmingham, England, John Roebuck began producing sulfuric acid in lead-lined chambers, which were stronger and less expensive and could be made much larger than the glass containers that had been used previously.
