Reclamation of metallic values from aluminous dross

Claim 1

A METHOD OF RECLAIMING METALIC VALUES FROM ALUMINOUS DROSS CONTAINING A SUBSTANTIAL AMOUNT OF LARGE LUMPS COMPRISING THE STEPS OF INTIIMATELY TUMBLING SAID ALUMINOUS DROOSSS WITH A SALT FLUX IN SOLID FORM CONSISTING OF A MIXTURE OF SODIUM CHLORIDE, POTASSIUM CHLORIDE AND A SMALL BUT EFFECTIVE AMOUNT OF A FLUORIDE CONSTITUENT ADAPTED TO STRIP OXIDE COATING FROM ALUMINUM METAL VALUES CONTAINED IN SAID ALUMINOUS SDROSSS, IN A MANER CHARACTERIZED BY DVIOLENT CASADING OF SAID ALUMINOUS DROOSS AND SALT FULX MIXTURE TO BREAK UP SAID LUMPS OF SAID ALUMINOUS DROSS SAID FLUX BEING CHARACTERIZED BY A MELTING POINT NOT GREATER THAN 1380 DDEGREES F., MELTING SAID SALLT FLUX BY APPLYING SUFFICIENT HEAT TO SAID ALUMINOUS DROSS AND SALT FLUX MIXTURE, MAINTAINING SAID MIXTURE AT A TEMPERATURE RANGING FROM 1350*. TO 1500 * F., AND THEN STRIPPING THE OXIDES FROM SAID DDROSS BY THE ACTION OF SAID MLOTEN FLUX TO RELEASE MOLTEN ALUMINOUS VALUES WHILE TUMBLING SAID MIXTURE IN A MANER SCHARATERIZED BY A GENTLE ROLLING ACTION, SAID VALUES AGGLOMERATING IN A MOLTEN METAL POOL AND SAID MOLTN FLUX BEING PRESENT IN AM AMOUNT TO ALSO PROVIDE A PROTECTIVE COVERING FOR SAID MOLTEN ALUMINOUS VALUES THEREBY SUBSTANTIALLY PREVENTING LOSSES OF ALUMINUM METAL DDUE TO OXIDATION AND BURNING.
