..Extraction of Sulphur
Extraction of Sulphur - Sulphur is extracted from underground deposits by pumping superheated steam (-440 K) down the beds to melt the element and then blowing out the molten sulphur with compressed air. This process is known as Frasch process. ..

Occurrence and Extraction
Sulphur occurs in the earth's crust to the extent of 0.05% mostly as metal sulphides and sulphates. It also occurs in the elemental form in large underground beds. Another major source of sulphur is H 2 S present in the natural gas and crude oil. Sulphur exists in comb..
