註釋The Stanrock Uranium Mines, Limited, initiated the production of a uranium concentrate in April of 1958. The laboratory and pilot plant evaluation of Stanrock concentrate is presented in this report. This concentrate meets all FMPC impurity tolerance limits except that for thorium content. The thorium limit can be met by the addition of phosphate as required for thorium-containing uranium concentrates. Laboratory digestion and extraction tests indicate that this material should present no problems in pulse column processing. A Pilot Plant pulse column test (a test utilizing a modified two-inch-pulse-column system) indicated that this material should present no operational problems in the National Lead Company of Ohio refinery.
