ABSTRACT:
A method for removing an impurity from a liquid metal in which: a flow of the liquid metal containing the impurity is passed into a chamber containing a quantity of the liquid metal and an electrolyte in which the impurity dissociates to form positive and negative ions; a voltage is applied between a pair of electrodes disposed respectively in the electrolyte and liquid metal to effect electrolytic extraction of the ions from the electrolyte; a flow of liquid metal is extracted from the chamber for circulation through an associated equipment; and an appreciable quantity of the electrolyte is circulated with the extracted liquid metal.
