    Sulphuric Acid Production from Pyrite at Cockle Creek

    Sulphuric acid has been manufactured at Cockle Creek Works since 1913, when the first chamber nitration plant was commissioned. The raw material was brimstone roasted in Herreschoff furnaces. Since that time three additional chamber units have been constructed and have produced acid from brimstone, zinc concentrates, pyrites and -spent oxide, according to changing economic and supply factors.

    CPM LCA Database Production of sulphuric acid by

    The phosphoric acid is imported from Kemira Chemicals in Finland who produces their sulphuric acid by roasting of pyrite. The sulphuric acid is then used to produce phosphoric acid. As no information of production of this sulphuric acid by roasting of pyrite was found, it was assumed that roasting of sulphide is equivalent concerning generation of steam. The dataset is included in aggregated datasets for
