Where does sulphur come from?

Sulphur is a volcanic product. It has many industrial uses. The volcanoes of Sicily and Japan were once the world’s chief suppliers.

Today important sources are in Texas and Louisiana in the United States. In the coastal regions there are underground sulphur domes. Two pipes, one inside the other, are forced down to the domes. Super heated steam is pumped down one of the pipes, melting the sulphur which is then forced up the other pipe. This method provides 92% of the United States output.

The other source is from sulphides of various metals which are called “pyrites”, It is the main source of sulphur in Sicily and Japan today.
