About Sulphur

Sulphur (or sulfur as our American customers say) is a yellow non-metallic chemical element which can be found in
group 16 (formerly VIB) of the periodic table. It's chemical symbol is S.

The element occurs naturally in many sulphide and sulphate minerals and native sulphur is also found in in most volcanic regions around the globe. It is extracted in its natural state through the Frasch process. It can also be obtained from hydrogen sulphide by the Claus process where Canada is the main producer source of sulphur for industry.

Solid sulphur occurs principally in three forms ( rhombic, monoclinic and amorphous), all of which are brittle, yellow in colour, odourless, tasteless, and insoluble in water. Although sulphur is infamous for its smell, frequently compared to rotten eggs, that odour is actually characteristic of hydrogen sulphide (H2S).

Sulphur is important for humans because it is part of the amino acid methionine, which is a dietary requirement. The amino acid cysteine also contains sulphur. The average person takes in around 900 mg of sulphur per day, mainly in the form of protein.
