Global Acid Rock Drainage Guide

The GARD guide is wiki-structured in a series of chapters that can be accessed through the main page. The guide deals with the prediction, prevention, and management of drainage produced from sulphide mineral oxidation, often termed “acid rock drainage” (ARD), “saline drainage” (SD), “acid mine drainage” or “acid and metalliferous drainage” (AMD), “mining influenced water” (MIW), and “neutral mine drainage” (NMD). The GARD Guide also addresses metal leaching caused by sulphide mineral oxidation. While focused on mining, the technology described will be helpful to those practitioners that encounter sulphide minerals in other activities (e.g., rock cuts, excavations, tunnels). Some of the approaches in the GARD Guide are also relevant to issues arising from reactive non-sulphide minerals. Tailings are one of the materials covered in the guide as they often have potential to produce acid and metalliferous drainage.
