Progress up-date on mine-site rehabilitation in Quebec

Symposium Rouyn-Noranda 2002
Abstract Until the early 1980's, rehabilitation of mine tailings ponds after mine closures only totalled about 400 hectares. It's a good thing things have changed since; indeed, at the present time, not only are the areas systematically rehabilitated after definitive closure but mining companies have already rehabilitated or are currently doing so at their old sites. Practically speaking, more than 3400 hectares, with about a third concerning acid areas, have undergone rehabilitation work over the last 20 years; this represents about half the cumulative inactive area since the beginnings of this industry on our territory and it places Quebec as a leader on a world scale in this field.

The major challenge now facing us is the rehabilitation of 69 so-called abandoned accumulation areas; this represents costs estimated at 67 to 75 million dollars.
