Iron ores (most in the form of taconite, because deposits rich in magnetite and hematite have been largely exploited) are mined, processed to remove noniron components, and smelted into metallic iron. Major sites of iron mining include South Africa, the United States, Australia, China, Russia, Japan, Ukraine, India, and Brazil.

Full-scale mining began in 1918 when 17,000 tons of oil shale was mined by open pit. By 1940, annual production of oil shale had reached 1.7 million tons. However, it was not until after World War II, during the Soviet era, that production increased dramatically, peaking in 1980 when 31 million tons of oil shale was mined by 11 open-pit and underground mines.

Processing the iron ore Onboard the IMV the processing plant will use magnetic separation and for a portion of the seperated sediment a grinding mill is required to lightly grind the sediment to separate the iron ore concentrate. This process will be completed wet using seawater. No heat, chemicals or additives will be used in the process.

2018-7-11 The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...
