Mine and Industrial complex at Koshkar-Ata, Kazakhstan Mine and Industrial complex at Koshkar-Ata, Kazakhstan
Before industrial operations started in the 1960s, the Koshkar-Ata hollow was a periodic lake rich in natural salt, making it unsuitable for farming. The discovery of vast uranium deposits in the deserts of western Kazakhstan lead to the establishment and rapid development of a uranium extraction and processing industry. At its peak in the 1980s Kazakhstan was producing more than a third of Soviet uranium, with more than 30 uranium mines. ...

Land mines in the Balkans Land mines in the Balkans
Some 11 countries in Europe (Western, Central Europe and the Balkans) are affected by anti-personnel mines. Several Balkan countries are severely affected as a result of the recent armed conflicts. However, the long-term legacy of anti-personnel mine contamination is also apparent in this region, where some countries are still removing anti-personnel mines laid during the Second World War.

Gold production of the Ok Tedi mine Gold production of the Ok Tedi mine
The Ok Tedi mine is located high in the rain forest covered Star Mountains of Papua New Guinea. Prior to 1981 the local Wopkaimin people lived a subsistence existence in one of the most isolated places on earth. That was before the 10 000 strong town of Tabubil suddenly appeared in the middle of their community. The Ok Tedi mine was built on the world’s largest gold and copper deposit (gold ore capping the main copper deposit).

Mining effects on rainfall drainage Mining effects on rainfall drainage
The Acid Mine Drainage (AMD) is the number one environmental problem facing the mining industry. AMD occurs when sulphide-bearing minerals in rock are exposed to air and water, changing the sulphide to sulphuric acid. It can devastate aquatic habitats, is difficult to treat with existing technology, and once started, can continue for centuries (Roman mine sites in Great Britain continue to generate acid drainage 2000 years after mining ceased)....

Mercury pollution - transport and cycle Mercury pollution - transport and cycle
Mines use toxic chemicals including cyanide, mercury, and sulphuric acid, to separate metal from ore. The chemicals used in the processing are generally recycled, however residues may remain in the tailings, which in developing countries are often dumped directly into lakes or rivers with devastating consequences. The accidental spillage of processing chemicals can also have a serious impact on the environment. For example, at the Baia Mare mine ...

Mining waste rock Mining waste rock
Regardless of the type of raw material, its extraction always comes with an environmental cost. Most mining leaves a lasting and damaging environmental footprint. For example, during the extraction of common metals like copper, lead or zinc from the earth both metal-bearing rock, called ore, and “overburden”, the dirt and rock that covers the ore are removed. At a typical copper mine around 125 tonnes of ore are excavated to produce just one ton...

Industrial hot spots Tisza river basin Industrial hot spots Tisza river basin
On 30 January 2000 a tailings dam at the Aurul Mine in Romania overflowed and released 100,000 cubic metres of effluent containing cyanide into the Tisza River. By the time the overflow was detected, the alarm raised and emergency measures taken to staunch the flow, heavily contaminated wastewater had reached the Danube River and was on its way to Hungary and beyond. Traces of cyanide, albeit at a very low level, were still detected in the rive...

Radioactive waste in Taboshar Radioactive waste in Taboshar
The Taboshar uranium mining site stands on the southern edge of the Kuramin Mountains close the Uzbek - Tajik border. The site consists of a non - rehabilitated open mine, dismantled production buildings, and three tailing sites storing 10 m tones of low grade processed uranium ore. The town of Taboshar with its 12000 inhabitants is only a few kilometers away.

Heavy industry in the Caucasus ecoregion Heavy industry in the Caucasus ecoregion
The Caucasus region is important in terms of heavy industry. Being rich with natural mineral resources, extraction industry is playing an important role in the overall economic development. However, concerns related to unsustainable mining practices increasingly worries the public. Within the Southern Caucasus, Armenia displays the greatest number of mine sites and identified mineral deposits. Within Armenia, the mining industry is concentrated i...

Natural resources - minerals Natural resources - minerals
In more than hundred countries around the world, miners dig minerals and metals out of the ground, satisfying a slowly but continuously increasing demand from industrial production, agriculture, construction, high-tech sectors, and merchandise producers. In contrast to the other natural resources presented here, minerals are a finite resource, and the resource and their profits needs to be managed carefully to ensure sustained livelihoods after t...

Mining exploration Mining exploration
The mining industry is a potential threat to Sumatran orangutan habitat in a number of important areas, both directly by its own activities and indirectly by road access. It includes a major gold mine near the town of Batang and iron ore mining in the Alas valley, and planned development of coal mining in the hill forests inland of the Tripa swamps.

Iron mine threats Beluga in Ban Island Iron mine threats Beluga in Ban Island
A large iron mine, operated by the Baffinland Iron Mines Corporation, has now been proposed in Baffin Island, with possibly severe impacts on wildlife on the island, such as development across the calving grounds of the caribou, and the establishment of two major ports. A 149 kilometres railway is planned, 100 kilometres of roads, 83 quarries (producing ca. 29,500,000 tons), and in an operation phase with an estimated traffic of 110 trucks per da...
