Understand Frasch process for extraction of sulphur. Click on the link to Watch the VIDEO explanation: Watch Video
It is based on the fact that sulphur has a comparatively low melting point. The Frasch pump consisting of three concentric pipe is sunk deep into sulphur bed. Super heated water in pumper under pressure in outer most pipe. This melts the sulphur present in the sulphur bed. Compressed air is pumped in the inner most pipe. This forces the mixture of water and molten sulphur to rush out through the middle pipe. This mixture of molten sulphur is collected. On cooling about 99% pure sulphur get separated.
