Rehabilitation of the Joutel Poirier Mine site: Acquired experience and work monitoring

Symposium Rouyn-Noranda 2002
Abstract The Poirier Mine site in Joutel was rehabilitated between 1998 and 2001. The main element of the work was the rehabilitation of the tailings pond and the spill zones, which totalled 4.5 million tonnes of tailings, spread over 74 hectares. The tailings are strong generators of acid mine drainage.

The first part of the presentation will comprise a brief review of rehabilitation concepts followed by a description of the main elements of the work with emphasis on what was learned from carrying out this work.

The second part of the presentation focuses on the results of the monitoring program, which has been going on since the work was finished in 2001. Monitoring elements deal with a lower water level within the cell, the settling of the tailings in the cell, the temperature and oxygen measurements within the cell and finally the improvement in surface water quality.
