    Tailings from sulphide ore contain sulphide and must be covered to prevent weathering. In certain cases, tailings can be used to backfill cavities. The amount of tailings that occurs is related to the contents of the ore. Higher content, like in iron ore mines (often over 60 per cent), results in less tailings.
