Abstract
A layer of electrolyte in pulverulent form is spread over the free surface of a liquid metal to be desulfurized, in which the layer provides cationic conductivity by means of a cation adapted to react with the sulfur contained in the metal. The electrolyte layer is contacted with a first electrode connected to the positive pole of a direct current supply and the metal is contacted by a second electrode connected to the negative pole of the current supply.
