Advantages Of Silver Electrolytic Refining

The electrolytic process of goldrefining possesses three advantages that are important in mintwork First it produces purer gold than the old processes The elimination of the last trace of silver from the gold removes the brittleness from the ingots used for coinage so that they roll and press much better than alloys of the same fineness in gold but made of slightly impure gold
