Rio Tinto Madagascar
Mandena mine (also Mandena operation, Mandena concession, or the QMM mine) is an ilmenite mine operated by Rio Tinto (corporation), Rio Tinto subsidiary QIT Madagascar Minerals (QMM). It is located near Taolagnaro, Fort-Dauphin (Madagascar), Fort Dauphin, Anosy region, Madagascar. The mine was first discovered in 1986 in an environmentally fragile and important region. Mining activity has been met with mixed reactions from the local community, with some protesting in 2013 and 2022. Pollution from the mine reached nearby Lake Besaroy in 2014 and 2015, before the mine's owners admitted there was no Tailings dam, tailing dam on site. Rio Tino promised to improve the environmental protection at the mine in 2004, but walked that promise back in 2016. Description Mandena is a titanium dioxide ore, and ilmenite mine on the Mandena concession, 5km northeast of Taolagnaro, Fort Dauphin.Frank Harris, (2019Transport and Export of Rare Earth Concentrates, Rio Tinto (corporation), Rio Ti ...

Fort-Dauphin (Madagascar)
Fort-Dauphin (Malagasy Tolagnaro or Taolagnaro) is a city (''commune urbaine'') on the southeast coast of Madagascar. It is the capital of the Anosy Region and of the Taolagnaro District. It has been a port of local importance since the early 1500s. A new port, the Ehoala Port was built in 2006–2009. Fort-Dauphin was the first French settlement in Madagascar. History The bay of Fort-Dauphin was found by a Portuguese Captain in 1500. Fort Dauphin was founded on an Antanosy village, Taolankarana, in 1643 by the French East India Company who built a fort there named in honor of the crown prince, the future Louis XIV of France. It was settled by around a hundred colonists, who found themselves involved in the local politics. The poor trade results (some ebony and little more was obtained) hardly justified the difficulties of the settlers, who suffered from tropical illnesses and other problems. After a conflict with the Antanosy people, the survivors were evacuated in 1674. One ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Open-pit Mines
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique that extracts rock (geology), rock or minerals from the earth. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface where the overburden is relatively thin. In contrast, deeper mineral deposits can be reached using underground mining. Open-pit mining is considered one of the most dangerous industrial sector, sectors in the industrial world. It causes significant effects to miners' health, as well as damage to the ecological land and water. Open-pit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths. Additionally, open-pit produces harmful pollutants depending on the type of mineral being mined, and the type of mining process being used. Extraction Miners typically drill a series of test holes to locate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mining Industry Of Madagascar
The mining industry of Madagascar is mostly on a small scale, centred mainly around remote locations with large mineral deposits. Mining potential is noted in industrial and metallic minerals, energy, precious and semi-precious stones, as well as ornamental stone. The mining sector was neglected by the government for decades prior to the mid-2000s. In 2013, the mining industry, a main source of foreign investment, was struggling due to "low metals prices and distrustful companies", attributed to a 2009 coup. History Mining was a part of Madagascar's cultural lore dating back to the 15th century before it became a reality at the beginning of the 19th century. Speculations of valuable metal and mineral deposits in Madagascar came with the arrival of the Imerina people, also known as the Antimerina, Merina, or Hova people, in the 15th century when they established their small kingdom in central Madagascar. These speculations of valuable metal and mineral deposits are rooted in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environmental Effects Of Mining
Environmental impact of mining can occur at local, regional, and global scales through direct and indirect mining practices. Mining can cause erosion, sinkholes, Biodiversity loss, loss of biodiversity, or the Soil contamination, contamination of soil, Groundwater pollution, groundwater, and surface water by chemicals emitted from mining processes. These processes also affect the atmosphere through carbon emissions which contributes to climate change. Some mining methods (lithium mining, Phosphate mineral, phosphate mining, coal mining, mountaintop removal mining, and sand mining) may have such significant environmental and public health effects that mining companies in some countries are required to follow strict environmental and rehabilitation codes to ensure that the mined area returns to its original state. Mining can provide various advantages to societies, yet it can also spark conflicts, particularly regarding land use both above and below the surface. Mining operations r ...

Tailings Dam
A tailings dam is typically an earth-fill embankment dam used to store byproducts of mining operations after separating the ore from the gangue. Tailings can be liquid, solid, or a slurry of fine particles, and are usually highly toxic and potentially radioactive. Solid tailings are often used as part of the structure itself. Tailings dams rank among the largest engineered structures on earth. The Syncrude Tailings Dam, Syncrude Mildred Lake Tailings Dyke in Alberta, Canada, is an embankment dam about long and from high. The dam and the artificial lake within it are constructed and maintained as part of ongoing operations by Syncrude in extracting oil from the Athabasca oil sands; it is the largest dam structure on earth by volume, and as of 2001 it was believed to be the largest earth structure in the world by volume of fill. There are key differences between tailings dams and the more familiar Hydroelectricity#Conventional (dams), hydroelectric dams. Tailings dams are design ...

Madagascar People's Armed Forces
The Madagascar Armed Forces (, ) is the national military of Madagascar. The IISS detailed the armed forces in 2012 as including an Army of 12,500+, a Navy of 500, and a 500-strong Air Force. The armed forces were involved in the 2009 Malagasy political crisis. During World War II, Malagasy troops fought in France, Morocco, and Syria. History The rise of centralized kingdoms among the Sakalava, Merina and other ethnic groups produced the island's first standing armies, first equipped with spears, but later with muskets, cannons and other firearms. King Ralambo (1575–1612) raised the first standing army in the highland Kingdom of Imerina with a handful of guns, although for at least two centuries the armies of the Sakalava were much larger and better equipped, possessing thousands of muskets obtained principally through trade with European partners. By the early 19th century, however, the army of the Kingdom of Imerina was able to bring much of the island under Merina cont ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partners ...
