Includes bibliographical references (pages 66-70). "Between 1961 and 1976, the St. Lawrence Columbium (SLC) mine produced pyrochlore concentrate from a niobium-bearing carbonatite deposit near Oka, Québec. This report is concerned with the environmental signature of tailings generated by the processing of carbonatite ore. It describes their physical properties, their mineralogy, their bulk chemistry, and the chemistry of seepage draining from the tailings impoundment. …"-- Summary and conclusions, page 65.
