The spurt in iron ore industry has started in 1955 subsequent to India`s economic embargo. Iron ore mining in Goa is completely in the private sector. Iron ore reserves in Goa are variously estimated to be around 1000 million tonnes. The Iron ore deposits in Goa are fines oriented. Around 80% of the deposits are fines and the rest lumps.

During the early 1960's, iron ore was open-cut mined near Rosston in Nevada County. About 250 tons of iron ore were shipped in 1965, the last year of recorded production. In 1969, the U.S. Bureau of Mines calculated iron ore reserves in Arkansas to be 120 million long tons with an average grade of 30 percent iron.

The Mesabi Iron Range in Northern Minnesota has been a major producer of iron ore for over 100 years. Production has been from the 1.85 – billion-year –old Biwabik Iron Formation, an iron-rich sedimentary rock that is tilted gently to the south. Most of the known high-grade ore lies near the surface and has been already mined. Determining whether more high-grade ore may lie at
