This is a list of countries by iron ore production based on U.S. Geological Survey data. List. Rank Country Usable iron ore production (1000 tonnes) Year World: 2,500,000: 2019 1: Australia: 930,000
Nov 01, 2018 2 Iron ore production. The EU has 9 member states producing iron ore, including Sweden, Norway, Austria, Slovakia and Germany. However, Sweden and Norway are the only countries in which significant quantities of iron ore are mined (Fig. 1). The quantities of iron produced from the mined ore have been between 19.1 Mta and 21.8 Mta in recent years.
May 24, 2021 Australia ranks first among the world’s largest iron ore producing countries, with output totalling 900 million tonnes in 2020 around 37.5% of total world production. The country is also home to the world’s largest crude iron ore reserves,estimated by the US Geological Survey at
iron-ore basin in Europe, and one of the finest in the world. The magnitude of the iron-ore reserves of Lor-raine both German and French may be indicated by a brief description of the region in which these de-posits are located and a comparison with the total re-serves of Europe and with the leading iron-ore fields in other parts of the world.
