    Abstract

    As part of the work aimed at the exploitation of the uraniferous rock in southern Greenland a flotation process has been developed. The uranium- and thorium-bearing minerals, mainly lanthanide phospho-silicates, can be flotated selectively with oleic acid as collector and sodium silicate as a regulating agent. Experiments indicate that linoleic acid is a more efficient collector than oleic acid. A characteristic feature is the sensitivity to cations in the process water, which excludes the use of tap water for the experiments. On the other hand this has led to the utilization of lanthanum as an activator.
