Preparation of titanium slag composition

Claim 1

A METHOD OF SMELTING AN ILMENITE ORE WITH COKE IN AN ELECTRIC FURNACE TO PRODUCE AND SEGREGATE A SUBSTANTIALLY IRON-FREE HIGHLY REDUCED TITANIFEROUS SLAG AND SOLID METALLIC IRON WHICH COMPRISES: ADMIXING THE ILMENITE ORE WITH FROM 17 TO 23 PARTS COKE PER 100 PARTS ORE TO REDUCE THE TITANIFEROUS VALUES IN THE ORE TO THE REDUCED OXIDES OF TITANIUM AND THE IRON VALUES TO METALLIC IRON; CHARGING THE MIXTURE OF ILMENITE ORE AND COKE INTO AN ELECTRIC FURNACE; HEATING SAID MIXTURE TO A SMELTING TEMPERATURE OF FROM 1700* C. TO 2300* C. BY MAINTAINING AN ELECTRIC ARC ABOVE SAID MIXTURE TO FORM A FLUID HIGHLY REDUCED TITANIFEROUS SLAG AND REDUCED IRON VALUES IN THE FORM OF MOLTEN METALLIC IRON WHICH COALESCES FROM SAID FLUID SLAG OF A GLOBULE OF SEGREGATED MOLTEN IRON METAL BENEATH THE SURFACE OF SAID FLUID SLAG; ADDING A NEW CHARGE OF A SUBSTANTIALLY IDENTICAL MIXTURE OF ILMENITE ORE AND COKE TO SAID FLUID SLAG, THEREBY COOLING SAID SLAG AND QUENCHING SAID GLOBULE OF MOLTEN METALLIC IRON; HEATING THE NEW MIXTURE OF MATERIALS IN SAID FURNACE TO FORM A SECOND BODY OF FLUID HIGHLY REDUCED TITANIFEROUS SLAG AND A SECOND GLOBULE OF SEGREGATED MOLTEN IRON METAL BENEATH THE SURFACE OF SAID SECOND BODY OF FLUID SLAG; PERIODICALLY INTRODUCING ADDITIONAL SUBSTANTIALLY IDENTICAL CHARGES OF ADMIXED ILMENITE ORE AND COKE TO SAID FURANCE TO FORM ADDTIONAL FLUID HIGHLY REDUCED SLAGS AND GLOBULES OF MOLTEN IRON, AND TO SEQUENTIALLY COOL THE PREVIOUSLY FORMED FLUID SLAGS AND GLOBULES OF MOLTEN IRON METAL; SUBSEQUENTLY COOLING AND SOLIDIFYING THE CONTENTS OF SAID FURNACE; AND THEREAFTER SEPARATING THE SOLIDIFIED GLOBULES OF METALLIC IRON FROM THE HIGHLY REDUCED TITANIFEROUS SLAG.
