Beartooth Pipe Acid/Alkaline Rock Drainage (ARD) and Geochemical Characterization Plan (BHP Billiton, 2003)
1 January 2003Report
This Acid/Alkaline Rock Drainage and Geochemical Characterization Plan for the Beartooth Pipe at Ekati Diamond Mine describes predictive testing, operational monitoring, and waste rock management strategies to assess potential environmental impacts from mining waste rock storage. Geochemical testing indicates that biotite granite (>99% of waste rock) has low reactivity, while biotite schist and kimberlite require segregation and encapsulation strategies to prevent acid generation and control drainage chemistry.
