As a result, demand for iron ore is tied directly to the production of raw steel and the availability of high-quality ferrous scrap. World production of raw steel was at a record-high in 1989 and would have been even greater in 1990 and 1991 if political and socioeconomic events had not led to the disintegration and dissolution of the U.S.S.R.
In 2005, the iron content of ore produced in Africa amounted to 34.8 t compared with 32.1 t in 2000. Higher production from the Sishen and the Thabazimbi Mines in South Africa more than offset lower output in Egypt and Mauritania.
Experts from the international mining sector believe that South Sudan is most likely to have several untapped mineral and metal resources such as gold, copper, uranium, and iron ore. In 2010, the oil sector of Sudan accounted for 7.5% of the GDP, and the mining and quarrying sector accounted for 0.2%.

Spot iron ore prices. Source: Vale's website. As a result, a number of high-cost iron ore mines have been closed and suspended throughout the world in 2014, with up to 30% of low-grade iron mines shut down in China in 2014 alone.
Not all iron ore is created equal. The highest quality and most important iron ores for steelmaking are hematite (Fe2O3) and magnetite (Fe3O4). Hematite is the more sought-after ore and the preferred raw material in efficient steelmaking mills. It accounts for approximately 95% …
South Africa - Mining - Encyclopedia of the Nations
South Africa was among the top five countries in terms of reserves, ranking first in reserves of andalusite, chromite, gold, manganese, PGMs, and vanadium. De Beers, the South African mining giant, accounted for 94% of the country's diamond production and controlled 80% of the world's uncut diamond trade.
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, principally the utilization of magnetite and taconite. Iron-ore mining methods vary by the type of ore being mined.
