Description
Various techniques for controlling acid rock drainage, including water cover, soil cover, wood back cover, and the addition of limestone and phosphate rock, were evaluated. Lysimeter tests and indoor column experiments were performed on rock samples from two mines in New Brunswick and Quebec, and were monitored for 60 weeks. The water cover proved to be the most effective technique, while all the techniques performed better in the laboratory. The wood bark technique, however, actually increased acid production.
