Abstract
Molten metal containing suspended liquid and solid particles is passed preferably generally upwardly through a porous media so constructed and arranged such that the movement of the molten metal therethrough renders the suspended liquid particles gravity separable. The gravity separable liquid particles rise upwardly or settle downwardly so as to be removable from said molten metal for subsequent removal therefrom. An associated apparatus is also provided.
