Analytical data

Result GRADE RANGED BETWEEN 70 - 80% FLUORITE PROBABLY AVERAGING CLOSE TO 75% WITH SILICA LESS THAN 2% (CORNWALL & KLEINHAMPL 1964). GEEHAN (1946) STATES SOME ORE WAS SHIPPED DIRECTLY AT 85% FLUORITE WITH LIMESTONE AS CHIEF GANGUE MINERAL. MILL GRADE ORE RAN ABOUT 70% FLUORITE. PURPLE FLUORITE CONTAIN UP TO 0.02 % U3O8 (GARSIDE, 1973). METALLURGICAL TEST BY USB7 CONTAIN 77.5 % CAF2, 2.4 % IO2, 3.9 % CACO3, 2.9 % AL2O3, 3.4 % R2O3, 0.35 % FE, 3.6 % INSOL.
