Geoenvironmental characterization of ferroniobium slag, Saint Lawrence Columbium Mine, Oka, Québec / A.J. Desbarats, J.B. Percival, P. Pelchat, J. Sekerka, I. Bilot, I. Girard, and P. Gammon.: M183-2/8752E-PDF
"Between 1961 and 1976, the St. Lawrence Columbium mine produced pyrochlore concentrate from a niobium-bearing carbonatite deposit near Oka, Québec. Beginning in 1971, the pyrochlore concentrate was converted into ferroniobium alloy through an aluminothermic reduction process, which also yielded slag as a waste product. Uranium and thorium occurring as impurities within the pyrochlore are preferentially sequestered in the slag. This report is concerned with the environmental characteristics of the slag including its physical properties, mineralogy, chemistry, radioactivity, and the chemistry of its leachate. …"-- Summary and conclusions, page 54.
