Magnetite is an iron oxide ore, which belongs to the equiaxed crystal system, and its chemical formula is Fe3O4. The Mohs hardness of magnetite is 5.5~6.5. Like hematite, it has strong magnetism. In ancient times, it was also called a magnet. Magnetite is often formed in igneous, …

Background at Palabora mine. Open-pit mining commenced at Palabora in 1964 and ended in 2002 when the pit reached its final economic depth. The development of an underground mine to work the ore remaining below the pit bottom began during the final years of open-pit production, at a cost of $465m, with the prospect of a further 20 years' …

Although the majority of current steel production is supported by iron ore sourced from high-grade haematite deposits, the long-term growing demand for steel has led to higher raw material prices and opened the way for many new magnetite deposits to also be developed._x000D_ There is a rich and long history of magnetite ore processing in …

Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, mainly the utilization of magnetite and taconite.
