The New Jersey Geological Survey is a public service and research agency within the NJ Department of Environmental Protection. Founded in 1835, the NJGS has evolved from a mineral resources and topographic mapping agency to a modern environmental organization that collects and provides geoscience information to government, consultants, industry, environmental groups, and the public.
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.

Iron ore is the term applied to a natural iron bearing mineral in which the content of iron is sufficient to be commercially usable. Metallic iron, from which steel is derived, must be extracted from iron ore. By definition, steel is a combination of iron with a small amount of carbon.
Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.
Its principal use is in steelmaking, where it serves as a purifying agent in iron ore refining and as an alloy that converts iron into steel. Although the amount of manganese consumed to make a ton of steel is small, ranging from 6 to 9 kilograms, it is an irreplaceable component in the production of this fundamental material.
Iron ore is present in a number of places and geologic settings within Wisconsin. Iron ore can be defined on the basis of its iron content into low grade ore (taconite), which commonly contains 25 to 35% iron, and high grade ore, which contains 50 to 70% iron. Iron bearing ore minerals include oxides, carbonates, silicates, and, in some cases, sulfides.

Its output came in at 900 million metric tons (MT) of usable iron ore in 2018, or 560 million MT of iron content, says the US Geological Surveys most recent report on iron ore.
Iron Ore. The Kentucky Geological Survey gets many inquiries about iron slag or pig iron, a product of the iron furnaces. Pig iron is commonly mistaken for meteorites, and although this slag is metallic, heavy, and resembles meteorites, it is just a byproduct of a past mining industry.
The US Geological Survey (USGS) collects statistics for both usable iron ore production and actual iron content. In recent years, some sources listed China as the largest producer of iron ore. However, this calculation was based on crude iron ore production.

Iron ore production in the United States has undergone a period of decline in recent years. As of 2018 estimates suggest that there were just 49 metric tons of or produced in the U.S. This is a
China is endowed with crude ore reserves of about 23 Bt according to the US Geological Survey (USGS), although the China Geological Survey estimate is considerably higher at more than 70 Bt. However, China's reserves are relatively low grade, averaging about 31% Fe, and hence contain only 7.2 Bt of iron according to USGS estimates.

Geological Educational Resources for K 16. In 1996, the Education Committee of the Kentucky Geological Survey, in conjunction with the Kentucky Society of Professional Geologists, established the Earth Science Education Network (ESEN). Originally, the network provided a group of geologists who served as resource persons for teachers.
