This is a list of countries by iron ore production based on U.S. Geological Survey data. [a] List. Rank Country Usable iron ore production (× 1000 tonnes) Year World:
During the 20th century, the consumption of steel increased at an average annual rate of 3.3%. In 1900, the United States was producing 37% of the world's steel, but with post war industrial development in Asia and centralised investment by China, by 2017 China alone accounted for 50% , with Europe (including the former Soviet Union) down to 24 ...
World consumption of iron ore grows 10% per year [citation needed] on average with the main consumers being China, Japan, Korea, the United States, and the European Union. China is currently the largest consumer of iron ore, which translates to be the world's largest steel producing country.
In 2008, 2009, 2015 and 2016 output fell in the majority of steel-producing countries as a result of the global recession. In 2010 and 2017, it started to rise again. Crude steel production contracted in all regions in 2019 except in Asia and the Middle East. India is the 2nd leading producer of iron and steel industries. [citation needed]
Steel is an alloy composed of between 0.2 and 2.0 percent carbon, with the balance being iron. From prehistory through the creation of the blast furnace, iron was produced from iron ore as wrought iron, 99.82–100 percent Fe, and the process of making steel involved adding carbon to iron, usually in a serendipitous manner, in the forge, or via the cementation process.
Although in 2014, the US mined only 1.8 percent of all iron ore mined worldwide, the US was previously a much larger factor in the world iron ore market. From 1937 through 1953, US iron ore made up more than a third of the world's iron ore production; the proportion of world iron ore mined in the US peaked in 1945 at 56 percent.
The industry produced over 74 million net tons per year as of November 2024. [1] Most iron and steel in the United States is now made from iron and steel scrap, rather than iron ore. The United States is also a major importer of iron and steel, as well as iron and steel products.
Iron plays an essential role in marine systems and can act as a limiting nutrient for planktonic activity. [200] Because of this, too much of a decrease in iron may lead to a decrease in growth rates in phytoplanktonic organisms such as diatoms. [201] Iron can also be oxidized by marine microbes under conditions that are high in iron and low in ...
