GUANAJUATO/DRAFTING/BLACK GOLD .- The Canadian company Great Panther Silver shed thousand 200 gallons of toxic waste at the tasting River and close to the archaeological site El Rosario, in Guanajuato, It was reported the Federal Attorney of environmental protection (PROFEPA).
The Canadian company, that extracts gold and silver in the municipality of Guanajuato, is responsible for the spill of 840 gallons of tailings containment pools and others 360 gallons in the River on one of the roads leading to the mine and tasting.
Sludge or mine tailings are toxic substances generated after the extraction of minerals and metals as lead, zinc, copper, Silver and gold and they may represent a risk for the ecological balance, the environment and the health of the population, designates the Norma Oficial Mexicana NOM-141-SEMARNAT-2003.
An eight-inch pipe burst, in the area of benefit of El Rosario mine plant flotation, generating mine tailings leakage, Profepa explained. -

The company Great Panther (and the mining El Rosario) is polluting the water Guanajuato through its metal extraction processes, which for years have affected waste water quality in the reservoirs La Soledad and La Esperanza. The mining basins throws elements poured from the dam in Mina Cata across the river of the same name, will give the Guanajuato River and finally to the Purisima dam.
In the basin through which run the waters finally dammed in the dam of La Purisima there are more than fifty tailings dams that bring pollutants that settle in the dam. The president of the Board of SIMAPAG says that heavy metals which would be contaminating the dam are iron, manganese and selenium; that to be a collapse of a tailings dam, which would generate pollution in the dam of La Purisima could be very large, which could be provided with proper drains and monitor their stability. The mine waste called tailings pile and they form large volumes that eventually acquire consistency. In the El Cedro community thousands of tons of sludge were deposited, so this was surrounded by tailings. Among the mines best known are La Valencia, San Ramon, Cata and Rayas and many of them even continue to produce in the hands of Canadian companies . Great Panther, Gammond Endeavour Silver and Gold . The La Valencia mine in Guanajuato in 1760 became the most productive mine in the world, now these mines are held by Great Panther and other Canadian companies Landscapes A description of Mineworkers said: Dispute Begins in 2005 over the company Allegations That Great Panther HAD illegally acquired mining titles from the mining cooperative Local That operated in the area. In 2008, Local Authorities Investigated the lack of environmental controls at the mine and the effects of drilling on the local waters. In the same year heavy rains over the company's tailings dam topped releasing a slurry ladden with heavy metals into the streets of Guanajuatos outlying Neighbourhoods. The ore is processed to produce high quality, precious metal-rich concentrate, Which is Transported to smelters in Mexico and Europe, for extraction of silver and gold. The Processing Plant is located near the Central Cata shaft. . It Consists of a 3-stage crushing section, a grinding section, Consisting of three ball mills operated in parallel and a conventional flotation circuit with a full capacity of 1,200 tonnes per day Keywords: Guanajuato silver (history); tailings dams; heavy metals (See less)
