Abstract

Molten metal, such as aluminum is passed through a media of submerged contacting surfaces (138). Operating life is enhanced by periodic cleaning of the contact media (138) by a high flow gas purge. Molten metal such as the light metals aluminum and magnesium containing finely divided suspended particles may also be treated to remove particles. The molten metal containing such suspended particles is moved through the medium of submerged contacting surfaces (138). The molten metal preferably is then passed through inclined channels or passages in contact with inclined surfaces such as parallel plates (144). Buoyant particles and agglomerates collect on the underside of the inclined surfaces (147).
