extraction of sulphur by coal gas

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. ..

Extraction of Iron is done in many steps like oxidation, combustion, fusion, reduction, etc. During extraction cast iron is formed first which is then converted to wrought iron. Hematite is the ore that is used for extraction of cast iron. The ore is crushed into smal..

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 exis..

Principle - Sulphur has a low melting point of about 112 o C - 115 o..
