Description:
The host rocks are carbonatite and foskorite. Chalcopyrite is the most abundant ore mineral followed by bornite. Chalcocite is a subsidiary sulphide in the foskorite. Other sulphides are valleriite, cubanite and pyrrhotite (minor). Other important mineral by-products are titaniferous magnetite and apatite. Uranothorite is also recovered.
Origin:
This standard was made using ore sourced from Palabora Mining Company The Palabora complex is unique in that it hosts the only economic copper sulphide carbonatite orebody in the world.
