註釋
The Consolidated Denison Mines, Limited, have recently started to produce a uranium concentrate. The laboratory and pilot plant evaluation of Denison uranium concentrate is presented in this report. With the exception of thorium and chloride content, this material meets all FMPC impurity tolerance limits. The thorium tolerance limit can be met by the addition of phosphate as required for thorium-containing uranium concentrates. The chloride content can be lowered below the tolerance limit by blending this material with a high-quality concentrate. Digestion and extraction tests indicate that the concentrate should give acceptable performance when processed under the suggested conditions. That is, with the exception of a lower extraction column pulse frequency, the standard operating conditions should be used. A slightly reduced organic extract saturation may be necessary to prevent excessive uranium losses in the raffinate.
