<p>PROBLEM TO BE SOLVED: To provide a flux for ash squeeze for efficiently separating and recovering aluminum from aluminum dross.SOLUTION: A flux contains 25 to 55 mass% NaNOand, as components other than oxides, the total 45 to 75 mass% of at least one or more kind of NaCl and KCl which are chloride and at least one or more kind of NaSiF, AlF, KAlFwhich are fluoride, and the balance inevitable impurities, and has NaNOhaving particle diameter of 1.5 to 5 mm of 90 mass% or more based on total NaNO. Further, 20 mass% or less of any one or more kind of NaSO, NaCO, KNO, and KSOwhich are oxide may be contained instead of NaNO.</p> |
