LABORATORY AND PILOT PLANT EVALUATION OF BICROFT URANIUM CONCENTRATE

摘要

The laboratory and pilot plant evaluation of Bicroft uranium concentrate is presented in this report. Digestion and extraction tests have indicated that this concentrate should present no problems in the National Lead Company of Ohio Refinery process, using standard operating conditions. With the exception of thorium content, this concentrate meets all FMPC impurity tolerance specifications. The thorium specification can be met by the addition of phosphate as required for thorium-containing uranium concentrates. The fluoride content of this concentrate approaches the fluoride tolerance limit. Therefore, future receipts of this material warrant a close check of the level of this contaminant.
