A copper-(U-)(Zr-)apatite-vermiculite mine located near Phalaborwa in Limpopo Province (previously NE Transvaal). Apatite production occurred 1932-1934. Vermiculite production began 1946. Copper mining commenced 1965 and was fully operational by 1967.
The town name is Phalaborwa, the geological formation is the Phalaborwa Complex and the mine Palabora mine.
Ore is in the Phalaborwa carbonatite complex. The largest open-pit mine in South Africa. Owned by Palabora Mining Company, Ltd.; RTZ (Manager).
The Phalaborwa Complex covers an area of 1950 hectares and it consists mainly of a phlogopite- and apatite rich pyroxenite. This pyroxenite is intruded successively by a series of more differentiated rocks - foskorite (phoscorite), and olivine- magnetite- apatite- phlogopite rock and finally a central intrusion of sövite (transgressive carbonatite). The sövite intrusion shows an intimate relationship with foskorite. The sövite (50 hectares at the surface) is composed of calcite and magnetite with minor amounts of dolomite, apatite, chalcopyrite, bornite and various silicates. Furthermore, uraninite-thorianite and baddeleyite are important accessory minerals. The sövite is being mined by large-scale opencast methods mainly for copper with uranium, zirconium and minute amounts of platinum as by-products. The foskorite is mined for the extraction of phosphate. The resources of apatite from the foskorite and the pyroxenite are enormous.
