Abstract |
The environmental impact of mining on the ecosystem, including land, water and air, has become an unavoidable reality. Guidelines and regulations have been promulgated to protect the environment throughout mining activities from start-up to site decommissioning. In particular, the occurrence of acid mine drainage (AMD), due to oxidation of sulfide mineral wastes, has become the major area of concern to many mining industries during operations and after site decommissioning. AMD is characterized by high acidity and a high concentration of sulfates and dissolved metals. If it cannot be prevented or controlled, it must be treated to eliminate acidity, and reduce heavy metals and suspended solids before release to the environment. This paper discusses conventional and new methods used for the treatment of mine effluents, in particular the treatment of AMD. |

Abstract |
A multi-layered geosynthetic system that includes geosynthetic-clay liners (GCL) and a geonet-composite drain (GNGC) is being used to cap and stabilize a 178000 m(exp 2) heap-leach pad at the Summitville Mine Superfund Site in Colorado. Selected were materials on the basis of design requirements for permeability, strength, extreme site conditions and cost. The Summitville cleanup called for a heap-leach pad cap to provide a barrier that would prevent precipitation from infiltrating the pad material. This long-term remediation prevents the pile from becoming saturated and allowing water to overflow the downslope dike, which could cause instability to dike and pond. Three geosynthetic alternatives were proposed. The contractor, that was awarded the heap leach pad, phase 2 contract, decided for a geosynthetic clay liner cap placed directly on the redesigned slopes. Bentofix NW-8 was used as GCL and TexNet TN was selected as the geocomposite drain. Conformance testing, subgrade preparation review, geosynthetic installation/repair inspection and review of cover material placement, performed by independent construction-quality assurance, showed that GCL is a well-suited cap material for heap leach pads, where high wind, cold temperatures rain and high altitude hinder construction. The robust geosynthetic allowed on-site coarse material to be used in the subgrade and cover layer, which saved the cost of importing more expensive bedding material. |
