Abstract
Column leaching tests are used to compare the leaching characteristics of several types of uranium tailings. The leaching characteristics of gypsum and radium-226 from Elliot Lake uranium tailings, as influenced by the methods employed in obtaining the tailings samples, the manner in which the tailings are loaded into lysimeters, and the aerobic/anaerobic conditions of the leach tests, are investigated. The purpose of this study is to obtain information on the release of environmental pollutants from uranium tailings in a shorter period of time than can be obtained by hydrogeological methods. The leaching characteristics of gypsum and radium-226 from leach residues derived from two laboratory tests on Saskatchewan uranium ores are compared to those of Elliot Lake tailings. Washing the tailings with potassium chloride (2 M) solution prior to the leaching test, or incorporation of peat moss and/or limestone in the column leaching tests greatly decreases the concentrations of radium-226 in the effluents of the column leaching tests.
