Non-metallic flotation process

Claim 1

THE METHOD OF RECOVERING BERYLLIUM VALUES SUBSTANTIALLY FREE FROM FLUORSPAR AND CALCITE FOUND IN BERTRANDITE ORE CONSISTING OF (1) GRINDING THE ORE IN ABOUT A 60 TO ABOUT 70 PERCENT TOTAL SOLID AQUEOUS SLURRY CONTAINING, PER TON OF ORE, BETWEEN ABOUT 1 AND ABOUT 10 POUNDS OF SODA ASH, BETWEEN ABOUT 1 AND ABOUT 2 POUNDS OF A SILICATE SELECTED FROM SODIUM AND POTASSIUM METASILICATES AND ORTHOSILICATES, SODIUM AND POTASSIUM FLUOSILICATE, AND MIXTURES THEREOF, TO A PARTICLE SIZE SUCH THAT AT LEAST ABOUT 95 PERCENT WILL PASS THROUGH A 200 MESH SIEVE AND ABOUT 75 PERCENT WILL PASS THROUGH A 325 MESH SIEVE, TO MAKE A PULP, AND SUBSEQUENTLY ADDING WATER TO DILUTE THE SOLIDS TO ABOUT 25 TO ABOUT 30 PERCENT AND CONDITIONING THE PULP AT A TEMPERATURE OF FROM ABOUT 30*C. TO ABOUT 100*C. FOR A PERIOD OF FROM ABOUT 2 TO ABOUT 20 MINUTES AND (2) PASSING A GAS WHICH IS CHEMICALLY INERT TO THE PULP UPWARDLY THROUGH THE PULP IN THE PRESENCE OF BETWEEN ABOUT 0.5 AND ABOUT 5.0 POUNDS, PER TON OF ORE PRESENT, OF A C8 TO C24 CARBOXYLIC ACID AT A CONTROLLED RATE, AT A PULP TEMPERATURE OF BETWEEN ABOUT 30*C. AND ABOUT 100*C., WHEREBY BOTH CALCITE AND FLUORSPAR ARE CAUSED TO RISE AS A FROTH AND TO OVERFLOW AS A CONCENTRATE, THUS EFFECTING A SEPARATION THEREOF FROM THE BERYLLIUM VALUES.
