SWEDEN — The Global Acid Rock Drainage (GARD) Guide was launched at the Eighth International Conference on Acid Rock Drainage held in Skelleftea last summer. The guide describes proven techniques for characterization, prediction, monitoring, treatment, prevention, and management of drainage produced by sulphide mineral oxidation, called “acid rock drainage” (ARD). It also addresses metal leaching caused by sulphide mineral oxidation.

 

The GARD Guide (www.GARDGuide.com) follows the “wiki” model, relying heavily on expert contributors to advance its store of technical knowledge. Already 700 pages have been compiled, and the project is moving into the phase of continuous improvement and awareness. It is intended to help industry improve its environmental protection, to allow government to assess and regulate mining activities, and enable to public to gain a higher degree of understanding of acid prevention plans and practices.

 

Users of the GARD Guide can leave comments and suggestions on the wiki website or provide feedback directly to Canmet’s Gilles Tremblay in Ottawa, at gilles.tremblay@nrcan.gc.ca.
