Remote mine site acid rock drainage treatment Foote, M. W.; Jordan, D. M.


As a part of the Mine Waste Technology Program (MWTP) a pilot-scale technology was tested for the remediation of acid mine drainage at a remote mine site. A remote mine site is one without infrastructure or power sources. The technology chosen for this demonstration was the AQUA-FIX (system) because of its capability to run with minimal operator assistance in a self regulating manner. Weather conditions, variable flow rates, and drainage compositions were considered during the design phase. For this demonstration, acidic drainage treatment consisted of removing toxic, dissolved, metallic and nonmetallic constituents from acidic mine drainage and increasing pH such that the pH of the effluent was near neutral. The MWTP is funded by the U.S. Environmental Protection Agency (EPA) and is jointly administered through an interagency agreement with the U.S. Department of Energy (DOE). Work was conducted through the DOE Federal Energy Technology Center at the Western Environmental Technology Office under the DOE Contract Number DE-AC22-96EW96405. The project was intended to illustrate the viability and feasibility of using the technology to remove numerous contaminant species from an aqueous point source discharge for up to one year.
