Abstract

1,205,634. Recovering zinc from dross. FOSECO INTERNATIONAL Ltd. April 22, 1968, [May 8, 1967], No. 21228/67. Headings C7D and C7M. Zinc is recovered from the ash formed by surface oxidation of a bath of molten zinc (e. g. being used for hot dipping) by treating it, either on the surface of the bath or separately, with composition, preferably anhydrous, comprising magnesium chloride and a refractory filler. The chloride preferably comprises 50-95% of the composition, and the filler 5-50% thereof. Other metal chlorides (such as of zinc) may be added, any zinc chloride preferably containing less than 1% zinc oxide impurity and the refractory filler (e.g. grog) preferably contains at least 25% thereof Al2O3. A composition comprising ZnCl2, MgCl2 and a refractory filler, which last contains at least 25% Al2O3, is preferred.
