2014 Workshop on Acid and Metalliferous Drainage 28 April - 2 May 2014 | Adelaide, South Australia
The triennial 8th Australian Acid and Metalliferous Drainage (AMD) Workshop is presented by SMI Knowledge Transfer (SMI KT), a unit within JKTech with cooperation from the Department of Manufacturing, Innovation, Trade, Resources and Energy (DMITRE), Government of South Australia. The workshop and associated short course and site visits will provide excellent opportunities to share with speakers and delegates, unbiased expertise and advocacy with respect to the causes, management and amelioration of the impacts of AMD and Acid Sulphate Soils.
The workshop theme, “What’s Working, What’s Not and What Could Be”, emphasises the need for companies to ensure their AMD risk assessment processes truly communicate a clear message to senior management, to learn from observations of the practical long-term implications of climatic extremes and to integrate appropriate emerging treatment technologies and research into perpetuity maintenance.
Key sessions will include: The Business Case for Improved AMD Management; A Global View on Acid and Metalliferous Drainage; Future Implications for AMD Management in Australasia; and Managing AMD - What’s Working, What’s Not and What Could Be; which covers planning mined-waste storage structures, rehabilitation issues, treatment technologies, new research, regulatory issues, monitoring measures, and long-term risk assessment studies.
The workshop, with its extensive program of 45 plus presentations, field trips, poster display and exhibition booths will offer delegates the opportunity to experience some of Adelaide’s many unique offerings through the workshop’s exciting social program.
The program for the 8th Acid and Metalliferous Drainage Workshop included plenary discussions, keynote presentations, and technical presentations.
In April 2014, mining industry environmental specialists and engineers, geochemists, leading researchers, consultants, regulators and students from across Australia and around the world will gather in Adelaide to explore emerging trends and issues related to Acid and Metalliferous Drainage/Acid Rock drainage (AMD/ARD) assessment and remediation. This year’s program will consist of a one day short course, followed by a four day workshop and inclusive field trip.
