Treatment of complex ores

Claim 1

A PROCESS FOR SEPARATING MINERALS FROM CALCIUMCONTAINING COMPLEX ORES WHICH COMPRISES GRINDING THE ORES TO A SUFFICIENTLY FINE MESH TO FORM A SLURRY WITH WARM WATER ACIDULATED WITH AN INORGANIC ACID IN AN AMOUNT EQUAL TO APPROXIMATELY 1 PERCENT OF THECALCIUM CONTENT OF THE ORE, ADDING THERETO WITH AGITATION A PRODUCT OBTAINED BY ADMIXING WITH A FRACTION OBTAINED BY THE DESTRUCTIVE DISTILLATION OF GILSONITE, AND BOILING BETWEEN 430*F. TO 438*F. XYLENE, TRIETHANOLAMINE AND FINELY GROUND SILICON DIOXIDE, ADDING HYDROCHLORIC ACID IN AN AMOUNT EQUAL TO ABOUT ONE-FOURTH OF THE INORGANIC ACID PREVIOUSLY ADDED, HEATING THE ENTIRE MIXTURE UNDER PRESSURE, COOLING THE THEREBY OBTAINED MATERIAL, ADDING DISTILLED WATER THERETO AND THEN FACTIONALLY DISTILLING THE AQUEOUS MIXTURE, AND SEPARATING THAT FRACTION BOILING BETWEEN 310*F. AND 315*F., SAID PRODUCT BEING ADDED TO SAID SLURRY IN AN AMOUNT EQUIVALENT TO 1/4 OF 1 PERCENT OF THE ACID CONTENT OF THE SLURRY, HEATING TO 200*F. AND ADDING SODIUM BICARBONATE IN AN AMOUNT BY WEIGHT EQUIVALENT TO TWICE THE AMOUNT OF ACID IN THE SLURRY, CONTINUING AGITATION AND ADDING POTASSIUM IODIDE IN AN AMOUNT EQUIVALENT TO 2 PERCENT OF THE SODIUM BICARBONATE FOLLOWED BY ALUMINUM NITRATE IN AN AMOUNT EQUIVALENT TO 1 PERCENT OF POTASSIUM IODIDE, PERMITTING THE MATERIALS TO SETTLE AND SKIMMING OFF THE SCRUM FORMED, ADDING TO THE SEPARATED SCUM SODIUM SULPHATE IN AN AMOUNT EQUAL TO THE POTASSIUM IODIDE PREVIOUSLY ADDED, AND DRAWING OFF THE PRECIPITATE FORMED.
