METHOD FOR SEPARATING MOLTEN SALT PARTICLES FROM MOLTEN METAL

摘要

A method for separating finely divided molten salt particles from molten metal (5) comprises providing a body of molten metal (5) having a suspension of molten salt particles entrained therein and contacting the molten metal (5) with a coalescing medium (30) substantially unwettable by the molten salt particles. The particles of salt are collected on the medium (30) and permitted to agglomerate so as to be removed to the surface (7) of the molten metal (5). The method is useful for treating molten aluminum which was subjected to fluxing and filtering treatments to remove impurities therefrom.
