Elko Roundtable Discussions

Elko Roundtable Discussions

Conference: Elko Roundtable
Date: 2005 to Ongoing

Knight Piésold USA has been hosting the Elko Rountable since 2005, with an aim in creating an environment to discuss current practices, challenges, and accomplishments associated with the need for, and the advancement of, innovation. The roundtable forum encourages an exchange of ideas and information pertaining to broad topics revolving around the subject of innovations in heap leaching and mine waste management. Compared to traditional conferences and symposia, the forum provides a much less inhibited format for discussion.

Previous rountable discussions included:

  • Heap leach pad design, construction, and operation
  • Design, construction, and operation of tailings storage facilities
  • Site-wide water considerations
  • Mine closure and cover design
  • Strides toward sustainability in mining
  • High-density tailings, paste, and filtered tailings
  • Acid rock drainage for engineers and environmental scientists
  • Material co-disposal/co-placement in the mining industry
