BIBLIODOCUMENTAL Presents: Water if gold does not (second part)
open pit mining is an industrial activity, high environmental, social and cultural. Industrial activity is also unsustainable by definition, to the extent that the exploitation of the resource is exhausted.
open pit mining removes the top layer or overuse of the land to make accessible the extensive mineral deposits of low quality. Modern digging equipment, conveyor belts, the vast machinery, the use of new inputs, the use of explosives and pipelines now makes it possible to remove whole mountains in a matter of hours, making it profitable to extract less than one gram of gold per ton of material removed.
to exploit gold is scattered in tiny amounts in rocks, and extraction as in many parts of the world, given its low tenor, will open and use cyanide poison and lethal if swallowed or inhaled. The quarry is similar to that of Chuquicamata in Chile, where copper is extracted, also spread.
In Cajamarca Tolima. For the construction of the quarry, the enterprise must raze to the ground, vegetation, wildlife and small tributaries of the ravines The Colossus and The ARENA.
fractured material taken from the quarry which is then impregnated with cyanide process be stockpiled and spread the weathering of the acid drainage flowing into surface waters, damaging, ultimately, the chemical quality of river water Coello used in agriculture and water supply as the municipality of El Espinal-Tolima Chicoral, which make drinking water more than 25,000. Besides the high level of environmental pollution generated the dust raised by the explosion in the removal of material causing nearby towns wings affect lung diseases.
But do you think after this that the mine will generate Tolima development? Let's talk ... while we are drinking red wine.
