Further studies on the leaching of uranium ores from Elliot Lake, Ontario: M34-20/112E-PDF

“The uranium mines of Elliot Lake area in Ontario, Canada, were brought into production in the mid-1950's. At that time the extraction plants were designed to utilize an acid leaching process which, although adequate in that about 95 percent extraction of the uranium was attained, was not thoroughly understood. Because of this the plant operators found it necessary to make trial-and-error adjustments to the operating conditions, one of the more important of these being to increase the temperature of the pulp during leaching. It was found that as the leaching temperature increased the acid addition needed for acceptable extraction decreased, the combined effect being a reduction in operating costs. A recent laboratory study has served to clarify further this relationship between leaching temperature and acid requirement. At the same time the effects of other operating variables were also studied more thoroughly than had been done in the past. The results of this investigation, which are reported in this paper, not only supplied new information related to the extraction of uranium from the Elliot Lake ores, but also emphasized the fact that currently used processes may not be understood sufficiently. Consequently, it may be profitable for operators to study existing processes further before they embark on major process changes"--Abstract, p. i.
