Highlights

  • CLU-IN Webinar Series on Mining Sites - OSRTI's Technology Innovation and Field Services Division launched a CLU-IN webinar series on treatment technologies at mining sites in June 2012. Topics include technology transfer, innovative and ecological approaches to dealing with mining waste, reuse and recovery technologies, and other related focus areas. The webinars are held on a quarterly basis and listed under Upcoming Internet Seminars (below). Archives of past webinars can be found under Archived Internet Seminars, Videos, and Courses.
  • Region 10 Workshops on Hardrock Mine Geochemistry and Hydrology - EPA's Region 10, Office of Research and Development (ORD), and Office of Superfund Remediation and Technology Innovation (OSRTI) hosted a three-part webinar series in February and March 2013 that focused on evaluating the potential for contaminant release from hardrock mine sites. Topics included water chemistry, potential sources of contamination from mine sites, and mitigation and reclamation practices to protect natural resources.

Upcoming Internet Seminars

  • Using Biosolids and Coal Combustion Products for Soil Remediation at Mining Sites
    July 24, 2014 | 1:00-3:00 PM EST

    Presented by Dr. W. Lee Daniels, Professor of Environmental Soil Science at Virginia Tech, this webinar will focus on the use of biosolids, coal combustion products, and other soil amendments for soil remediation and revegetation at mining sites. The following topics will be presented:

    Utilizing biosolids as a soil amendment for mined land reclamation. This presentation will include an overview of the history of land application of biosolids to coal mined lands and other applications to mineral sands and sand and gravel mining, with a particular focus on predicting nitrate-N leaching losses.

    Remediation and revegetation of phytotoxic materials with biosolids and lime. This presentation will focus on the presenter's work in Poland and Virginia on the stabilization and revegetation of coal refuse, Pb/Zn smelter slags and tailings, and acid sulfate soil materials via the application of relatively high rates of biosolids and lime.

    Potentials and issues for use of coal combustion residuals (CCRs) in mined land reclamation. This presentation will focus on the potential benefits and risks of using CCRs such as fly and flue gas desulfurization (FGD) material in mined land reclamation as either surface soil amendments or bulk alkaline additions to acid-forming materials. This will include a brief synopsis of current regulatory development issues.

    All three presentations will include case study data and findings that are supported by publications available from the presenter and collaborators' website www.landrehab.org.

Upcoming Meetings

  • Life of Mine Conference 2014
    July 16-18, 2014 | Brisbane, Australia

    The 2014 Life of Mine Conference, organized by the Australia-Africa Mining Industry Group in collaboration with the University of Queensland's Centre for Mined Land Rehabilitation, focuses on current and future mine rehabilitation practices. Delegates from industry, government and research areas will join to share practical experiences from across the mining life cycle: from exploration and pre-feasibility stages, to mineral extraction and processing phases, and the post-operational closure era. In addition, the conference provides a platform for the mining and mineral processing engineers to be engaged with, learn from, and contribute to addressing the challenges and opportunities associated with the rehabilitation of mining and mineral processing wastes. Click here for program details and registration.

  • Water Management in Mining Summit
    July 29-30, 2014 | Denver, Colorado

    The 3rd Annual Water Management in Mining Summit brings together mining companies, site operators, regulators, and engineers to share best practices and explore viewpoints. The summit seeks to investigate the technical methods for dealing with tailings and acid mine drainage, as well as the regulatory atmosphere surrounding the water management process in order to ensure that mines achieve a comprehensive and holistic approach. It will also challenge participants' thinking on issues such as permitting, mine design development, depressurization, dust suppression, and developing Zero Liquid Discharge policies, among others. Click here for more information and to register for the summit.

  • Critical Minerals 2014 Conference
    August 3-5, 2014 | Denver, Colorado

    Hosted by the Society for Mining, Metallurgy & Exploration Inc. (SME) in partnership with AusIMM, Critical Minerals 2014 will focus both on rare earths and other critical minerals. The conference will evaluate where rare-earth markets are today, as well as identify and consider other elements and minerals that are or may become critical. The program will commence with overviews of those minerals considered critical and updates on national critical-materials strategies. The technical program will include presentations on specific markets and projects by leading geologists, mining engineers, metallurgists, financiers and developers. Click here to register.

  • National Conference on Mining-Influenced Waters: Approaches for Characterization, Source Control and Treatment
    August 12-14, 2014 | Albuquerque, New Mexico
    Sheraton Albuquerque Uptown Hotel

    The U.S. Environmental Protection Agency is sponsoring a national conference on mining-influenced waters in August 2014. The conference goal is to provide a forum for the exchange of scientific information on current and emerging approaches to assessing characterization, monitoring, source control, treatment and/or remediation on mining-influenced waters. Topics may include but are not limited to characterization, water treatment, beneficial use, source control/mine closure approaches, and prediction and modeling. Click here to register.
