[0002] The anode plate for wet electrolytic zinc is mainly obtained by remelting and casting the waste anode plate into a blank, and in the electrolytic refining or electrolytic extraction of the soluble anode, the anode contains a small amount or trace amount of other metals or elements in addition to the main body metal, which exist in the anode in the form of elements, alloys or compounds, and when the anode is polarized, the equilibrium potential of these metals or elements is positive to the anode potential, so they cannot ionize into the electrolyte, and part of them can ionize into the electrolyte, but immediately form insoluble salts with the electrolyte and precipitate from the electrolyte to become anode mud. The generated anode mud exists in the form of dispersed fine powder and adheres to the surface of the anode plate.

[0003] The waste anode plate adheres to a certain amount of anode mud, and in the operation of the anode furnace, the anode mud and a certain amount of smelting slag need to be salvaged from the anode furnace regularly to ensure the normal smelting process.
