註釋
The Northspan Uranium Mines, Ltd. started producing a uranium concentrate in December of 1957. The laboratory and pilot plant evaluation of Northspan uranium concentrate is presented in this report. Chemical analyses of this concentrate reveal that it meets all existing FMPC impurity tolerance limits, except that for thorium. The thorium tolerance limit can be met by the addition of phosphate, as is required for thorium-containing uranium concentrates. Digestion and extraction tests indicate that this concentrate should present no problems in the FMPC refinery process if standard operating conditions are used.
