hey...dear..here is your answer.....❤️❤️

The Frasch process is a method to extract sulfur from underground deposits. It is the only economic method of recovering sulfur from elemental deposits. In the Frasch process, superheated water is pumped into the sulfur deposit; the sulfur melts and is extracted. The Frasch process is able to produce high purity sulfur.

In the Frasch process, three concentric tubes are introduced into the sulfur deposit. Superheated water (165 °C, 2.5-3 MPa) is injected into the deposit via the outermost tube. Sulfur (m.p. 115 °C) melts and flows into the middle tube. Water pressure alone is unable to force the sulfur to the surface due to the molten sulfur’s greater density, so hot air is introduced via the innermost tube to froth the sulfur, making it less dense, and pushing it to the surface.



The sulfur obtained can be very pure (99.7 – 99.8 %). In this form, it is light yellow in color. If contaminated by organic compounds, it can be dark-colored; further purification is not economic, and usually unnecessary.☺️☺️

hope it helps you....✌️✌️

Using this method, the United States produced of sulfur in 1989, and Mexico produced of sulfur in 1991.

A working demonstration model of the Frasch process suitable for the classroom has been described.
Hope it help you.
