Water Treatment: Iron Mountain Mine and Bunker Hill Mining and Metallurgical Complex Superfund Sites
December 17, 2014 | 1:00-3:00 EST
More Information & Registration
This webinar features three presentations on mining-influenced water (MIW) treatment delivered at the 2014 National Conference on Mining Influenced Waters. The session focuses on approaches to MIW treatment, operations and maintenance (O&M) challenges, and characterization and remediation of MIW treatment issues at two Superfund sites.
- Iron Mountain Mine Superfund Site — Long Term O&M Challenges
Nearly 100 years of mining at the Iron Mountain Mine Superfund Site in Shasta County, California resulted in extensive workings and fractured rock, creating pathways for air and water to oxidize the massive sulfide ore. This resulted in the development of MIW with pH as low as -3.6 and the release of tens of thousands of pounds of heavy metals per day into the surrounding drainages and water bodies, before remediation reduced metals loading by more than 97%. This presentation will discuss some of the long-term and unusual O&M issues at the site, which include mineral precipitate formation in MIW conveyance pipelines, accelerated deterioration of a urethane liner in an uncontaminated water diverter, loss of filtrate from a lined pit used to store high-density sludge, and deterioration of concrete ore chute plugs that are part of MIW collection systems.
- Characterization and Remediation of Iron(III) Oxide-Rich Scale in a Pipeline Carrying Acid Mine Drainage at Iron Mountain Mine, California, U.S.A.
A pipeline carrying acid mine drainage (AMD) to the treatment plant at the Iron Mountain Mine Superfund Site (California, U.S.A.) has developed substantial scaling over the past several years, resulting in spillage of AMD and requiring frequent and costly clean-out. This presentation will discuss some of the research being conducted by USGS at this site on these issues. The objectives of the work are to characterize the pipe scale composition, identify biogeochemical processes leading to its formation, and identify possible strategies to prevent or retard its formation in the pipeline.
- Tackling AMD, Mining Impacted Groundwater, Private Mine Ownership in a Superfund Site that Spans the Panhandle
Historic disposal practices at the Bunker Hill Mining and Metallurgical Complex Superfund Site led to the mining-related hazardous substances being dispersed in nearly every aspect of the environment. EPA and the Idaho Department of Environmental Quality has undertaken cleanup actions to address exposure to lead and other heavy metals, and excellent progress has been made from both aesthetic and risk reduction standpoints. However, significant loading of dissolved metals continues to occur and many more years of work are necessary to fully achieve the cleanup goals for human health and water quality standards. This presentation will provide a brief history of the site, including EPA ownership and management of the water treatment plant, provide an in-depth look at the 2MGD+ Acid Mine Drainage water quality (a groundwater collection system currently being designed), and discuss recent optimization study and value engineering exercises that were pursued to ensure the most cost effective remedial action.
Society for Mining, Metallurgy & Exploration 2014 Conference
December 7-8, 2014 | Tucson, AZ
Through its annual, topical, and regional meetings, the Society for Mining, Metallurgy & Exploration provides opportunities for the critical exchange of information that enhances the professional and the industry. These programs are designed for and by the men and women who work to advance mineral science. This conference delivers a strong technical program addressing the broad spectrum of mining technologies, concepts, and solutions.
10th ICARD & IMWA Annual Conference
April 21-24, 2015 | Santiago, Chile
The 10th International Conference on Acid Rock Drainage (ICARD) and the International Mine Water Association (IMWA) Annual Conference will be held as a single conference in Santiago, Chile in 2015. The conference will be a unique opportunity to gather the newly-formed local and South American acid drainage and mine water community. Conference themes include geomicrobiology; biogeochemical cycles and biomining; applied mineralogy and geoenvironmental units; prediction of drainage flow; prediction of drainage chemistry; mine water and drainage collection and treatment; dry covers; scaling from laboratory to field studies; reliable mine water operation; mine water management for closure; mine water geochemistry. Registration is open and can be completed at http://www.icard2015.com/english/registration.
2015 Joint National Conference of ASMR and ARRI
June 6-11, 2015 | Lexington, KY
The 32nd Annual Meeting of American Society of Mining & Reclamation (AMSR) and the 9th Annual Meeting of the Appalachian Regional Reforestation Initiative (ARRI) will be held jointly from June 6 to 11, 2015. Stay tuned for more details. A call for abstracts has recently been issued for the conference with a December 1, 2014 submission deadline.
2015 Annual Conference of the Mining History Association
June 11-14, 2015 | Virginia City, NV
The 2015 Annual Conference of the Mining History Association (MHA) returns to Virginia City, Nevada, June 11-14, 2015. Virginia City was the location of the first MHA meeting in 1990 as part of the Western History Association conference. For its 25th — Silver — Anniversary, the MHA will return to the Comstock Lode, site of America's first great silver boom, for a series of events, tours, and sessions. Stay tuned — the conference program will be available in early 2015.
