ASPECTOS GEOQUIMICOS-AMBIENTALES DEL CIANURO EN LOS DEPOSITOS DE COLAS ABANDONADOS

Abstract

There is now overwhelming evidence that, despite concerns to the contrary, natural degradation ofcyanide and cyanide attenuation by hidrogeochemical processes are capable of minimizing or eliminating thepotential harmful effects, that on the living things or the environment, can be generate from a decommissionedheap leach environment. The cyanide species that are likely to exist within an abandoned heap leach system willbe identified, and the relative toxicity and potential environment effect of these cyanide species will be discussed.
