Iron ore ore rich in iron or the element Fe

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe

Liberia republic in West Africa

Liberia, officially the Republic of Liberia, is a country on the West African coast. It is bordered by Sierra Leone to its northwest, Guinea to its north, Ivory Coast to its east, and the Atlantic Ocean to its south-southwest. It covers an area of 111,369 square kilometers (43,000 sq mi) and has a population of around 4,900,000. English is the official language and over 20 indigenous languages are spoken, representing the numerous ethnic groups who make up more than 95% of the population. The country's capital and largest city is Monrovia.

Grand Gedeh County County in Zwedru, Liberia

Grand Gedeh is a county in the eastern portion of the West African nation of Liberia. One of 15 counties that constitute the first-level of administrative division in the nation, it has three districts. Zwedru serves as the capital with the area of the county measuring 10,484 square kilometres (4,048 sq mi). As of the 2008 Census, it had a population of 126,146, making it the ninth most populous county in Liberia. Grand Gedeh has lower tropical forests which has mid size hills composed of various valleys and water courses. These forests receive a very high rainfall ranging from 3,000 mm (120 in) to 4,100 mm (160 in) per year.

Iron ore production in Africa is dominated by South Africa, Mauritania and Algeria; Zimbabwe and Morocco produce ore for use within the country. Many countries possess iron ore deposits that are as yet untapped/unmined. Countries and companies currently involved in production are listed here; measurements are in tpy, or tonnes per year.

The Liberian-American-Swedish Mining Company (LAMCO) is a defunct Liberian corporation that mined for iron ore in the Nimba range in Liberia. Founded in 1955 by American and Swedish investors, the company established the first large-scale mining operation in Liberia following the discovery of the Nimba ore body by geologist Sandy Clarke in the 1950s. A standard gauge railroad approximately 360 km long was built, linking the mine in the north of the country, to the Port of Buchanan. The Nimba project was managed by LAMCO, Bethlehem Steel and the Liberian government. A nationalization policy was introduced to gradually phase out the non-Liberian staff. In November 1989, LAMCO was taken over by LIMINCO and under a ten-year contract managed by AMCL. Operations were disrupted, but never damaged, several times beginning in September 1990, and were halted in January 1994 when ships were no longer willing to pick up ore at the Port of Buchanan. Soon after operations were halted, LIMINCO's sites at Yekepa and Buchanan were pillaged which continued until 2004. Today, the former LAMCO mining operation is being reactivated by Arcelor Mittal.

Mining industry of Ivory Coast

Although the subsoil of Ivory Coast contained many other minerals, none existed in commercially exploitable amounts, given the high costs of extraction. Mining contributed only 1 percent of GDP in 1986.

India–Liberia relations are the foreign relations between India and the Republic of Liberia. India is represented in Liberia through its embassy in Abidjan and an active honorary consulate in Monrovia since 1984. Liberia was represented in India through its resident mission in New Delhi which subsequently closed due to budgetary constraints.

Railways in Liberia

Railways in Liberia comprised two lines from the port of Monrovia in the northeast, and one line from the port of Buchanan in the centre. The principal traffic is, or was, iron ore. In 2010, only the Bong mine railway was operational but the Lamco Railway was at least partially rebuilt by Arcelor Mittal and put back into service in 2011.

Mining industry of Liberia

The mining industry of Liberia has witnessed a revival after the civil war which ended in 2003. Gold, diamonds, and iron ore form the core minerals of the mining sector with a new Mineral Development Policy and Mining Code being put in place to attract foreign investments. In 2013, the mineral sector accounted for 11% of GDP in the country and the World Bank has projected a further increase in the sector by 2017.

The geology of Liberia is largely extremely ancient rock formed between 3.5 billion and 541 million years ago in the Archean and the Neoproterozoic, with some rocks from the past 145 million years near the coast. The country has rich iron resources as well as some diamonds, gold and other minerals in ancient sediment formations weathered to higher concentrations by tropical rainfall.
