Canatuan Mine
The Canatuan mine was a gold/silver, copper/zinc open-pit mine located in the province of Zamboanga del Norte on the southern island of Mindanao, Philippines. The mine was operated from 2004 to January 2014 by TVI Resource Development (Phils) Inc., a former subsidiary of Canadian-based TVI Pacific Inc. The mine was operated within Mount Canatuan, a sacred mountain of the Subanen people, who protested against the mining company and its operations. Mining history Gold panning activity in the Canatuan Creek area was first recorded in the mid 1980s. The substantial quantities of gold being recovered prompted prospecting efforts to find the bedrock source of the gold. In 1990 prospectors discovered an extensive field of gold-bearing boulders and the first test pit was sunk that year. Reports of the discovery drew experienced artisanal and small scale miners (SSM's) from elsewhere in the Philippines, as well as local people to form several small co-operatives. By 1994, the area was be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper Mining
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using mineral flotation. The concentrate is typically sold to distant smelters, although some large mines have smelters located nearby. Such colocation of mines and smelters was more typical in the 19th and early 20th centuries, when smaller smelters could be economic. The sulfide concentrates are typically smelted in such furnaces as the Outokumpu or I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold Mines In The Philippines
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental (native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gol ...

Survival International
Survival International is a human rights organisation formed in 1969, a London based charity that campaigns for the collective rights, rights of indigenous peoples, indigenous and/or tribal peoples and uncontacted peoples. The organisation's campaigns generally focus on tribal peoples' desires to keep their ancestral lands. Survival International calls these peoples "some of the most social vulnerability, vulnerable on earth", and aims to eradicate what it calls "misconceptions" used to justify violations of human rights. It also aims to publicize harm caused to tribes by corporations and governments. Survival International states that it aims to help foster tribal people's self-determination. Survival International is in association with the United Nations Department of Public Information, Department of Public Information of the United Nations and in consultative status with the United Nations Economic and Social Council. To ensure freedom of action, Survival accepts no governm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KAIROS
Kairos ( grc, καιρός) is an ancient Greek word meaning 'the right, critical, or opportune moment'. In modern Greek, ''kairos'' also means 'weather' or 'time'. It is one of two words that the ancient Greeks had for 'time'; the other being (). Whereas the latter refers to chronological or sequential time, ''kairos'' signifies a proper or opportune time for action. In this sense, while is quantitative, ''kairos'' has a qualitative, permanent nature. The plural, () means 'the times'. Kairos is a term, idea, and practice that has been applied in several fields including classical rhetoric, modern rhetoric, digital media, Christian theology, and science. Origins In Onians's 1951 etymological studies of the word, he traces the primary root back to the ancient Greek association with both archery and weaving. In archery, ''kairos'' denotes the moment in which an arrow may be fired with sufficient force to penetrate a target. In weaving, ''kairos'' denotes the moment ...

Subanon People
The Subanon (also spelled Subanen or Subanun) is an indigenous group to the Zamboanga peninsula area, particularly living in the mountainous areas of Zamboanga del Sur and Misamis Occidental, Mindanao Island, Philippines. The Subanon people speak Subanon languages. The name is derived from the word ''soba'' or ''suba'', a word common in Sulu, Visayas, and Mindanao, which means "river", and the suffix ''-nun'' or ''-non'', which indicates a locality or place of origin. Accordingly, the name ''Subanon'' means "a person or people of the river". These people originally lived in the low-lying areas. However, due to disturbances and competitions from other settlers like the Moros, and migrations of Cebuano speakers to the coastal areas attracted by the inviting land tenure laws, further pushed the Subanon into the interior. The Subanon are traditionally farmers and regularly move from one location to another to clear more forest for fields. They cultivate crops, with rice as the mos ...

Sediment Control
A sediment control is a practice or device designed to keep eroded soil on a construction site, so that it does not wash off and cause water pollution to a nearby stream, river, lake, or sea. Sediment controls are usually employed together with erosion controls, which are designed to prevent or minimize erosion and thus reduce the need for sediment controls. Sediment controls are generally designed to be temporary measures, however, some can be used for storm water management purposes. Commonly used sediment controls * Check dam *Diversion dike (temporary) * Fiber rolls * Gabions * Siltbusters * Sand bag barrier * Sediment basin * Sediment trap * Silt fence *Storm drain inlet protection * Straw bale barrier *Turbidity curtain Active treatment systems Chemical treatment of sediment, commonly called an active treatment system, is a relatively new form of sediment control for the construction industry. It is designed to reduce turbidity in nearby water bodies and involves collect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acid Mine Drainage
Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks containing an abundance of sulfide minerals. Areas where the earth has been disturbed (e.g. construction sites, subdivisions, and transportation corridors) may create acid rock drainage. In many localities, the liquid that drains from coal stocks, coal handling facilities, coal washeries, and coal waste tips can be highly acidic, and in such cases it is treated as acid rock drainage. This liquid often contains highly toxic metals, such as copper or iron. These, combined with reduced pH, have a detrimental impact on the streams aquatic environments. The same type of chemical reactions and proc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open-pit Mine
Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburden is relatively thin or the material of interest is structurally unsuitable for tunnelling (as would be the case for cinder, sand, and gravel). In contrast, minerals that have been found underground but are difficult to retrieve due to hard rock, can be reached using a form of underground mining. To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting ea ...
