520 | 3 |a"During 1982 the Environmental Protection Service conducted a lab experiment to; 1) determine the oxidation potential of mine tailings from several abandoned mines in the Yukon, and 2) to determine in the iron-oxidizing bacteria, Thiobacillus ferrooxidans, was present and if it was contributing to the oxidation process. A fresh sample of tailings from Cyprus Anvil Mining Corporation was used as a reference because of its well known oxidation potential. Though all four abandoned mines tested were theoretical acid produces only two mines showed oxidation potential. The results, overall, suggest that T. ferrooxidans is present at each mine location but is not necessarily active. Tailings at two mines showing no oxidation potential possess acid consuming ability which is probably the prime factor inhibiting bacterial activity. The study showed this small scale experiment is useful in determining oxidation potential of mine tailings and also indicated the need for further assessment of the oxidation potential of the Wellgreen nickel mine and the Arctic mine"--Abstract, page i. |
