METHOD AND DEVICE FOR DISSOLVING AND SEPARATING ALUMINUM FROM RAW MATERIAL CONTAINING ALUMINUM AND METALS WITH HIGHER MELTING POINT THAN ALUMINUM

摘要

PROBLEM TO BE SOLVED: To provide a method and device for dissolving and separating aluminum combined metals containing iron materials or copper materials which need no special device, can easily control temp. of a molten metal and make a crucible furnace as an original model. SOLUTION: A crucible 3 in which a tap hole 6 is through-formed in the vicinity of intermediate height of a drum part is installed upward in a furnace main body 1 and is heated from an outer periphery thereof. A raw material containing aluminum and metal with higher melting point than that of aluminum is charged in the crucible 3 and aluminum is melted in the crucible 3. Molten aluminum stored in the crucible 2 is discharged to outside from the tap hole 6. The raw material is additionally charged in the crucible 3 timely and by proper quantity so as to keep a state that unmolten aluminum always exists in the molten aluminum in the crucible 3.
