How Is Sulfur Mined? | Reference

The Frasch process is a way of harvesting deep lying sulphur from the ground that was developed by chemist Herman Frasch. In this process, water is heated to 170 degrees Celsius and pumped down into the earth, where it melts the sulfur. The sulfur is then lifted to the surface using compressed air and put into huge vats where the water slowly ...

The Frasch process is used to mine sulfur from underground deposits. Larger amounts of sulfur also come from hydrogen sulfide recovered during the purification of natural gas. Sulfur exists in several allotropic forms. The stable form at room temperature contains eight-membered rings, and so the true formula is S 8. However, chemists commonly use S to simplify the coefficients in chemical equations; .
