Once USA was the highest iron ore-producing country of the world. As indicated in Table 8.1, the percentage of world production of iron ore was 18.1 in 1960 and 9.8 in 1975. But now it produces less than 4 per cent of the world’s production and ranks 7th. The four main iron ore-producing regions of USA are Lake Superior region, north-eastern region, south-eastern region and western region.
Iron ore-producing areas are widely distributed in the world. There are about 60 countries in the world, which produce iron ore.
It is often used when large quantities of steel are needed, for example as structural steel. The density of mild steel is approximately 7.85 g/cm3 (7850 kg/m3 or 0.284 lb/in3)[4] and the Young's modulus is 210 GPa (30,000,000 psi).
According to the American Iron and Steel Institute (AISI), in the week ending October 3, 2015, US domestic raw steel production was 1,727,000 net tons while the capability utilization rate was 72.2 percent. Production was 1,862,000 net tons in the week ending October 3, 2014 while the capability utilization then was 77.4 percent. The current week production represents a 7.3 percent decrease from the same period in the previous year. Production for the week ending October 3, 2015 is down 0.5 percent from the previous week ending September 26, 2015 when production was 1,735,000 net tons and the rate of capability utilization was 72.6 percent. Adjusted year-to-date production through October 3, 2015 was 67,819,000 net tons, at a capability utilization rate of 72.5 percent. That is down 8.0 percent from the 73,727,000 net tons during the same period last year, when the capability utilization rate was 78.0 percent.
