The deposit will be mined using conventional opencut mining methods including drilling, blasting, loading and hauling. The pit depth is expected to be approximately 300m. Magnetite ore will be mined at a rate of 80Mt/y. Overburden and waste will amount to 80Mt/y annually.
Kumba Iron Ore at Sishen, near Kathu, is a typical example. Owned by Anglo American, Africas largest iron ore producer and the tenth largest in the world, Kumba operates a massive, singlepit, open cast mine that stretches 13 km north to south, and km across at its widest point. As the mine deepens, the width is expected to reach 5 km.
industry and typically involves smelting to convert iron ore into pigiron (in South Africa primarily via the blast furnace route) and then refining (eg using a basic oxygen furnace) and shaping it in rolling mills into steel products (eg HRC hot rolled coil). Other input materials in steel manufacturing are scrap, manganese and coking coal.
