Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries.
List of countries by iron ore production Wikipedia
World iron ore production (thousands of tonnes) in 2013/2015: This is a list of countries by iron ore production based on U.S. Geological Survey data. The mine production estimates for China are estimated from the National Bureau of Statistics China's crude ore statistics, rather than usable ore as reported for the other countries.
The report found global iron ore production will grow modestly from 3,322mnt in 2019 to 3,430mnt by 2028. This represents average annual growth of 0.2% during 2019 2028, which is a significant slowdown from an average growth of 4.5% during 20092018.
For these reasons, iron ore production is concentrated in the hands of a few major players. World production averages two billion metric tons of raw ore annually. The world's largest producer of iron ore is the Brazilian mining corporation Vale, followed by AngloAustralian companies Rio Tinto Group and then BHP Billiton.
Higher iron ore grades boost the furnace's productivity by sparing slag volume in the blast oxygen furnace (less coke/lime usage) as well as demonstrating a higher permeability with the gasses. Rio estimates for every 1% of increased iron ore grade the productivity is 2% higher for the Chinese mills centred in the north.
The mine production of iron ore in the United States reached approximately 55 million metric tons in 2011. Until 2017, the annual production decreased to estimated 46 million metric tons. Iron ore mine production. Iron ore are rocks and minerals that can be heated in
Coal is the most important sector and accounts for 24 percent of total mining production, followed by PGMs (23 percent) gold (16 percent) iron ore (12 percent) other nonmetallic minerals (6 percent) diamonds (4 percent) manganese ore and chromium ore (3 percent each) other metallic minerals, building materials and nickel (2 percent each), and copper (1 percent).
