Method for melting and treating aluminum

Claim 1

A METHOD OF MELTING ALUMINUM METAL COMPRISING THE STEPS OF PROVIDING A BODY OF FUSED SALT IN A FIRST CHAMBER, SAID SALT CONSISTING ESSENTIALLY OF MIXTURE OF SODIUM CHLORIDE, POTASSIUM CHLORIDE AND A FLUORIDE CONSTITUENT AND HAVING A DENSITY LESS THAN THAT OF SAID METAL AND BEING AT A TEMPERATURE SUFFICIENT TO MELT SAID METAL, SUCH SALT ADAPTED TO STRIP OXIDE COATING FROM THE ALUMINUM, WITHDRAWING SAID FUSED SALT FROM SAID FIRST CHAMBER AND INTRODUCING THE SALT INTO A SECOND CHAMBER IN A MANNER TO CREATE AGITATION THEREIN INTRODUCING ALUMINUM METAL INTO SAID AGITATED FUSED SALT IN SAID SECOND CHAMBER THEREBY CAUSING INTIMATE MIXTURE OF SAID FUSED SALT WITH SAID METAL IN SAID SECOND CHAMBER, PASSING SALT AND METAL INTO A THIRD CHAMBER FROM BELOW THE SURFACE OF THE FUSED SALT IN SAID SECOND CHAMBER INTO THE THIRD CHAMBER AND BELOW THE SURFACE THEREIN, SUBSTANTIALLY ALL OF SAID METAL FUSING IN SAID SECOND AND THIRD CHAMBERS, THE RESULTING GLOBULES OF FUSED METAL SETTLING TO THE BOTTOM OF SAID THIRD CHAMBER AND SAID FUSE SALT FROM THE THE SURFACE THEREOF, AND WITHDRAWING FUSED SALT FROM THE SURFACE OF THE SALT IN SAID THIRD CHAMBER AND RETURNING SAID SALT TO THE BODY OF MOLTEN SALT IN SAID FIRST CHAMBER.

Claim 2

A METHOD OF MELTING ALUMINUM METAL COMPRISING THE STEPS OF PROVIDING A BODY OF FUSED SALT IN A FIRST CHAMBER, SAID SALT CONSISTING ESSENTIALLY OF MIXTURE OF SODIUM CHLORIDE, POTASSIUM CHLORIDE AND A FLUORIDE CONSTITUENT AND HAVING A DENSITY LESS THAN THAT OF SAID METAL AND BEING AT A TEMPERATURE SUFFICIENT TO MELT SAID METAL, SUCH SALT ADAPTED TO STRIP OXIDE COATING FROM THE ALUMINUM, WITHDRAWING SAID FUSED SALT FROM SAID FIRST CHAMBER AND INTRODUCING THE SALT INTO A SECOND CHAMBER IN A MANNER TO CREATE AGITATION THEREIN INTRODUCING ALUMINUM METAL INTO SAID AGITATED FUSED SALT IN SAID SECOND CHAMBER THEREBY CAUSING INTIMATE MIXTURE OF SAID FUSED SALT WITH SAID METAL IN SAID SECOND CHAMBER, PASSING SALT AND METAL INTO A THIRD CHAMBER FROM BELOW THE SURFACE OF THE FUSED SALT IN SAID SECOND CHAMBER INTO THE THIRD CHAMBER AND BELOW THE SURFACE THEREIN, SUBSTANTIALLY ALL OF SAID METAL FUSING IN SAID SECOND AND THIRD CHAMBERS, THE RESULTING GLOBULES OF FUSED METAL SETTLING TO THE BOTTOM OF SAID THIRD CHAMBER AND SAID FUSE SALT FROM THE THE SURFACE THEREOF, AND WITHDRAWING FUSED SALT FROM THE SURFACE OF THE SALT IN SAID THIRD CHAMBER AND RETURNING SAID SALT TO THE BODY OF MOLTEN SALT IN SAID FIRST CHAMBER.
