Brief note on the method of mining sulphur

Underground sulphur is mined by using a special technique known as "Frasch process". This process is based on the fact that sulphur has comparatively lower melting point. In the Frasch process, a hole is bored into the sulphur beds. Through this hole three concentric pipes are pushed. Through the outermost tube, superheatd water is forced down.
