Sulphur Production & Uses Nuroil

Sulphur is used in the manufacture of carbon disulphate, sodium thiosulphate, gun powder, matches and in fireworks. Sulphur is used on vulcanization of rubber. Natural rubber is soft and sticky. Heating it with sulphur makes it hard non-sticky and more elastic. This process of heating of natural rubber with sulphur is known as vulcanization.

SO2 (Sulfur Dioxide) Air Mining SGS

The SO 2 air process is relatively simple and invariably cost-effective. During the process, sulfite ions react with atmospheric oxygen and a copper catalyst as follows: 2CN- + Na 2 S 2 O 5 + 2O 2 + 2OH- --> 2CNO- + Na 2 SO 4 + SO 4 2-+ H 2 O. The SO 2 process offers a number of advantages over other cyanide destruction methods including:

What is Sulfide Mining? Mining Action Group

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water
