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.
World proved coal reserves are currently sufficient to meet 134 years of global production, much higher than the R/P ratio for oil and gas By region, Asia Pacific holds the most proved reserves (41% of total), split mainly between Australia, China and India.
The country has rich reserves of gold, iron ore, chromium, manganese, titanium, nickel, copper, lead, platinum, tungsten, phosphates, tin and diamonds. About one-fifth of the timber in the entire world is present in the forests of Siberia. One-sixth of the iron ore reserves in the world can be found in the deposits of the Kursk Magnetic Anomaly.
World titanium reserves; Titanium is obtained from various ores that occur naturally on the Earth. Ilmenite (FeTiO3) and rutile (TiO2) are the most important sources of titanium. According to USGS, Ilmenite accounts for about 92% of the world's consumption of titanium minerals. World resources of anatase, ilmenite and rutile total more than 2 ...

Mineral or ore reserves are sub-divided in order of increasing confidence into probable mineral/ore reserves and proved mineral/ore reserves. A 'probable' mineral reserve (or probable ore reserve) is the economically mineable part of an indicated mineral resource.
World uranium reserves in 2010. Uranium reserves are reserves of recoverable uranium, regardless of isotope, based on a set market price. The list given here is based on Uranium 2016: Resources, Production and Demand, a joint report by the OECD Nuclear Energy Agency and …
Manganese is the 12th most abundant element in the earth's crust. According to the data released by USGS (United States Geological Survey), global manganese reserves are about 570 million tonnes (metal content) with land-based manganese resources distributing irregularly in 2014, and world manganese mine production was estimated to be 17 million tonnes in 2013.
In addition, recycling, innovation and mining exploration continue to contribute to the long-term availability of copper. Despite increased demand for copper produced from ore in recent years, increases in reserves have grown more, and there is more identified copper available to the world than at any other time in history.
Top 10 Countries with Largest Gold Reserves. July 5, 2018. Beginning in 2010, central banks around the world turned from being net sellers of gold to net buyers of gold. Last year official sector activity rose 36 percent to 366 tonnes – a substantial increase from 2016.
If an extremely high ore price is tolerable, then very low grades of uranium ore can be considered as possible reserves. As the permissible ore grade (uranium concentration) goes down, the amount of recoverable uranium (i.e., reserves) goes up exponentially.
Mineral reserves or Ore reserves are valuable and legally, economically, and technically feasible to extract In common mining terminology [ weasel words ], an "ore deposit" by definition must have an 'ore reserve', and may or may not have additional 'resources' [ citation needed ] .
Carajas is the world's biggest iron ore mine. Samarco Alegria iron ore mine is operated by a 50-50 joint venture between BHP Billiton and Vale. Zanaga in Congo is the world's fifth biggest iron ore mine. Simandou mine in southeast Guinea holds the sixth biggest iron ore reserves. Image courtesy of …

Till 1975 its percentage in world production of iron ore was 9.2. The main iron ore-producing areas are located in Itabiria in south-east Brazil. Itabiria is believed to be the richest iron ore reserves in the world – estimated reserves of 35,000 million metric tons.
World Mineral Production 2012-2016. The latest edition of this annual publication from the British Geological Survey (BGS) is now available to download.This volume contains mineral production statistics for the five year period from 2012 to 2016, for more than 70 mineral commodities, by country worldwide.

A deposit of copper-bearing minerals is classed as an ore reserve if there are sufficient quantities and con-centrations of minerals to be extracted at a profit.
Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode.
