    In contrast, other minerals such as pyrite (FeS 2) and chalcopyrite (CuFeS 2 the main ore mineral for copper in Cornwall) are sulphides, which can oxidise. In a wet oxygenated environment pyrite will oxidise to produce sulphuric acid and iron hydroxide as follows (Merefield 1995): 2FeS 2 + 7O 2 + 2H 2 O ® 2FeSO 4 + 2H 2 SO 4

    Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heat-resistant and does not conduct electricity.
