Preliminary Results of Sequential Extraction Experiments for Selenium on Mine Waste and Stream Sediments from Vermont, Maine, and New Zealand

By N.M. Piatak, R.R. Seal II, R.F. Sanzolone, P.J. Lamothe, and Z.A. Brown

We report the preliminary results of sequential partial dissolutions used to characterize the geochemical distribution of selenium in stream sediments, mine wastes, and flotation-mill tailings. In general, extraction schemes are designed to extract metals associated with operationally defined solid phases. Total Se concentrations and the mineralogy of the samples are also presented. Samples were obtained from the Elizabeth, Ely, and Pike Hill mines in Vermont, the Callahan mine in Maine, and the Martha mine in New Zealand. These data are presented here with minimal interpretation or discussion. Further analysis of the data will be presented elsewhere.
