Sumsar
Sumsar is a village in Chatkal District of Jalal-Abad Region of Kyrgyzstan. Its population was 2,802 in 2021. Until 2012 it was an urban-type settlement. It is situated in the foothills of the Chatkal Range. A lead and zinc mine was located in Sumsar. The mine was exploited by the Sumsar company who also operated a uranium mine in neighbouring Shekaftar. The company left behind three huge tailings site containing toxic waste: Most of Tailings No. 1 have slipped into the Sumsar river. Tailings No. 3 have never been covered, leaving a fine dust exposed to the wind. Tailngs No. 2 is also in need of repairs. The mill tailings of the lead and zinc milling in Sumsar and the low-grade uranium ore heaps in Shekaftar need an urgent remedial action because the legacy sites became chronic sources of toxic and radioactive contaminants for the Sumsar-Say River. The legacy sites are approximately 10–15 km upstream from the northern fringes of the Fergana valley that belongs to the most ...

Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It ...

Uranium Mine
Uranium mining is the process of extraction of uranium ore from the ground. Over 50 thousand tons of uranium were produced in 2019. Kazakhstan, Canada, and Australia were the top three uranium producers, respectively, and together account for 68% of world production. Other countries producing more than 1,000 tons per year included Namibia, Niger, Russia, Uzbekistan, the United States, and China. Nearly all of the world's mined uranium is used to power nuclear power plants. Historically uranium was also used in applications such as uranium glass or ferrouranium but those applications have declined due to the radioactivity of uranium and are nowadays mostly supplied with a plentiful cheap supply of depleted uranium which is also used in uranium ammunition. In addition to being cheaper, depleted uranium is also less radioactive due to a lower content of short-lived and than natural uranium. Uranium is mined by in-situ leaching (57% of world production) or by conventional unde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tailings
In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are different to overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining, which pulverizes the rock containing the ore and then relies on chemical reactions to concentrate the sought-after material. In the latter, the extraction of minerals from ore requires comminution, i.e., grinding the ore into fine particles to facilitate extraction of the target element(s). Because of this comminution, tailings consist of a slurry of fine particles, ranging from the size of a grain of sand to a few micrometres. Mine tailings are usually produced from the mill in slurry form, which i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toxic Waste
Toxic waste is any unwanted material in all forms that can cause harm (e.g. by being inhaled, swallowed, or absorbed through the skin). Mostly generated by industry, consumer products like televisions, computers, and phones contain toxic chemicals that can pollute the air and contaminate soil and water. Disposing of such waste is a major public health issue. Classifying toxic materials Toxic materials are poisonous byproducts as a result of industries such as manufacturing, farming, construction, automotive, laboratories, and hospitals which may contain heavy metals, radiation, dangerous pathogens, or other toxins. Toxic waste has become more abundant since the industrial revolution, causing serious global issues. Disposing of such waste has become even more critical with the addition of numerous technological advances containing toxic chemical components. Products such as cellular telephones, computers, televisions, and solar panels contain toxic chemicals that can harm th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fergana Valley
The Fergana Valley (; ; ) in Central Asia lies mainly in eastern Uzbekistan, but also extends into southern Kyrgyzstan and northern Tajikistan. Divided into three republics of the former Soviet Union, the valley is ethnically diverse and in the early 21st century was the scene of conflict. A large triangular valley in what is an often dry part of Central Asia, the Fergana owes its fertility to two rivers, the Naryn River, Naryn and the Kara Darya, which run from the east, joining near Namangan, forming the Syr Darya river. The valley's history stretches back over 2,300 years, when Alexander the Great founded Alexandria Eschate at its southwestern end. Chinese chroniclers date its towns to more than 2,100 years ago, as a path between Greek, Chinese, Bactrian and Parthian civilisations. It was home to Babur, founder of the Mughal Dynasty, tying the region to modern Afghanistan and South Asia. The Russian Empire conquered the valley at the end of the 19th century, and it became part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
