Mining remains are a world-wide problem, posing health and environmental risks, if
left without proper aftercare. Together with Mexican authorities site-specific
concepts have been elaborated that lead to sustainable improvement of
environmental situation and quality of life in the surrounding communities of mines,
situated in the state of Durango.
A passive-biological water treatment plant was built to clean cyanide and heavy
metal containing wastewater of ore processing facilities. The surface of a former
tailings pond was recultivated. The treated water is used to irrigate the newly
vegetated area. A specially developed computer-based data bank is supporting the
centralized safety and rehabilitation management of sites, which are potentially
hazardous to health and environment.
A manual for securing, restoration and reclamation of mining sites was elaborated,
which has since been serving the authorities and mine operators as a guideline
and decision aid.
