Operations started with a test mine in 1887. From 1891 to 1933, the business was registered as a Swedish company called Sulitelma Aktiebolags Gruber.
Pyrite oxidation by atmospheric O 2 in the presence of moisture (H 2 O) initially produces ferrous ions (Fe 2+) and sulfuric acid which dissociates into sulfate ions and protons, leading to acid mine drainage (AMD). An example of acid rock drainage caused by pyrite is the 2015 Gold King Mine waste water spill.
Between 1955 and 31 May 1972, iron sulphides (mainly as pyrite) was mined at the Nairne Pyrite Mine—later renamed as the Brukunga Mine—immediately west of the town, and transported to Port Adelaide for the production of sulphuric acid, used for manufacturing superphosphate fertiliser. [7]

The resulting chemical reactions oxides the sulfide minerals the gold is trapped within. [3]
