Rehabilitation of mining areas in Durango, Mexico
Rehabilitation of mining areas in Durango, Mexico Project: Engineering Services: 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. • Socio-economic and environmental risk assessments for three mining locations in Durango • Design and operation of passive-biological water treatment plant • • Recultivation planning for former tailings pond Development of a computer-based database of contaminated sites and for remediation planning Elaboration of an handbook for remediation and rehabilitation of mining sites • Period: 2008 - 2010 Contact person: Dr. André Gerth Figure: Passive-biological water treatment plant (left) and recultivation area (right) at silver mine La Parrilla in Durango Deutscher Platz 5 D- 04103 Leipzig, Germany +49 -341 / 224 58 30 +49 -341 / 224 58 31 [email protected] www.bioplanta-leipzig.de
