The Liganga mine is a large proposed iron mine located in Southern highland of Tanzania in the Ludewa District of Njombe Region. Road construction has begun in 2014. Ongaba represents one of the largest iron ore reserves in Tanzania and (perhaps) in the world having estimated reserves of 1.22 billion tonnes of ore grading 35% iron metal. [1]
Tanzania is a lower-middle income economy. Tanzania is largely dependent on agriculture for employment, accounting for about half of the employed workforce. The economy has been transitioning from a command economy to a market economy since 1985. Although total GDP has increased since these reforms began, GDP per capita dropped sharply at first, and only exceeded the pre-transition figure in around 2007.
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 color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe
3O
4, 72.4% Fe), hematite (Fe
2O
3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe).
Taconite is a variety of iron formation, an iron-bearing sedimentary rock, in which the iron minerals are interlayered with quartz, chert, or carbonate. The name "taconyte" was coined by Horace Vaughn Winchell (1865–1923) – son of Newton Horace Winchell, the Minnesota State Geologist – during their pioneering investigations of the Precambrian Biwabik Iron Formation of northeastern Minnesota. He noted the rock had a superficial resemblance to iron-bearing rocks from the Taconic Mountains of New York state.
Mining in Iran is still under development, yet the country is one of the most important mineral producers in the world, ranked among 15 major mineral-rich countries, holding some 68 types of minerals, 37 billion tonnes of proven reserves and more than 57 billion tonnes of potential reserves worth $770 billion in 2014. Mineral production contributes only 0.6 per cent to the country's GDP. Add other mining-related industries and this figure increases to just four per cent (2005). Many factors have contributed to this, namely lack of suitable infrastructure, legal barriers, exploration difficulties, and government control.

Mining in the United Kingdom produces a wide variety of fossil fuels, metals, and industrial minerals due to its complex geology. In 2013, there were over 2,000 active mines, quarries, and offshore drilling sites on the continental land mass of the United Kingdom producing £34bn of minerals and employing 36,000 people.

The mining industry of Guinea was developed during colonial rule. The minerals extracted consisted of iron, gold, diamond, and bauxite. Guinea ranks first in the world in bauxite reserves and 6th in the extraction of high-grade bauxite, the aluminium ore. The mining industry and exports of mining products accounted for 17% of Guinea’s gross domestic product (GDP) in 2010. Mining accounts for over 50% of its exports. The country accounts for 94% of Africa’s mining production of bauxite. The large mineral reserve, which has mostly remained untapped, is of immense interest for international firms.
The mining industry of Sudan was mostly driven by extraction fuel minerals, with petroleum accounting for a substantial contribution to the country's economy, until the autonomous region of Southern Sudan became an independent country in July 2011. Gold, iron ore, and base metals are mined in the Hassai Gold Mine. Chromite is another important mineral extracted from the Ingessana Hills. Other minerals extracted are gypsum, salt, and cement. Phosphate is found in Mount Kuoun and Mount Lauro in eastern Nuba. Reserves of zinc, lead, aluminium, cobalt, nickel in the form of block sulfides, and uranium are also established. Large reserves of iron ore have been established.
The Mtwara Development Project is a major infrastructure development project involving southern Tanzania, northern Mozambique, eastern Malawi and Eastern Zambia. The goal of this project is to provide road, rail and waterway access from the surrounding region to the Port of Mtwara. The region and the corridor has been neglected by the respective governments for over 40 years and the recent discovery of oil, gas and various minerals has kick started the development of the project. A road and rail link is to be built from the port of Mtwara to Mbamba Bay on Lake Nyasa to link Malawi to the corridor and further road links into Mozambique will facilitate access to northern Mozambique.
