The Sicilian method was one of the first ways to extract sulfur from underground deposits. It was the only industrial method of recovering sulfur from elemental deposits until it was replaced by the Frasch process. Heaps of sulfur were collected and set on fire, and the pure part that melted down was separated. The method takes its name from the Sicily region of Italy, which was then the center of sulfur production. Most of the world's sulfur was obtained this way until the late 19th century.
In petroleum and natural gas, a chemical process called the "Claus method" is applied to obtain sulfur.
There are different types of sulfur as powder, solid and liquid. They are separated according to their particle size and purity. Although the forms and physical properties of sulfur varieties are different, their chemical properties are the same. The best quality sulfur is 99,9 percent pure and 1-90 micron and 0,05 percent ash. Commercially used sulfur is 99 percent pure.
Sulfur types can be listed as follows;
- natural sulfur
- mineral sulfur
- industrial sulfur
- agricultural sulfur
- pharmaceutical sulfur
- soil sulfur
- leaf sulfur
- Powdered sulfur
- Elemental powdered sulfur
- Micronized powdered sulfur
- Granular sulfur…
USAGE AREAS OF SULFUR
Sulfur is among the basic substances of industrial production, especially sulfuric acid. Millions of tons of sulfur are used for the production of sulfuric acid, which is widely used in industry. Apart from sulfuric acid, it is used in the production of sulfur dioxide gas, carbon sulfide and thiosulfate.
We can list some products and sectors where sulfur, sulfuric acid and its compounds are used:
Chemical and agricultural industry, feed additives, synthetic resins, fertilizers and fertilizer additives, animal pesticides, pigments, petroleum products, detergents, sheet metal, explosives, some batteries, paper, insecticides, tyres, gunpowder, fireworks, matches, rubber, cosmetics, shampoos, fabrics, adhesives…
