A major source of limestone was quarried during 1942–81 by BHP at Rapid Bay, 80 km south of Adelaide, to supply metallurgical flux to the Whyalla, Newcastle and Port Kembla steelworks. The operations, including crushing plant, jetty and loading wharf, were purchased by Adelaide Brighton Cement Ltd in 1981.

The major use for lime is in metallurgy, primarily in steel production as a flux to remove phosphorus, sulfur, silica, and manganese from the molten steel. Lime is also used in aluminum and magnesium metal production and in the processing of other metal ores (copper, gold, nickel, zinc, cobalt, and lead).
