Lead anodes

Lead anodes for extractive metallurgy electrolysis

JL Goslar manufacturers complete lead anodes and anode plates for zinc and copper extraction electrolysis. Cast anodes are produced in all necessary alloys. Pb-Ag alloy anode plates for zinc electrolysis and Pb-Ca alloys for copper electrolysis are also made by rolling. Rolled electrodes have better density and grain structure than cast anodes, consequently offering ideal corrosion resistance and deformation stability. This results in a longer service life. Finally, the anode plates can be blasted in the special ABG procedure in accordance with customer specifications, to meet the special demands made by the electrolysis process.

  
   

The shape and size of the copper bar and the anode plate are made to customer specifications. The copper bar is tin-plated and then given a homogeneous coat of lead several millimetres thick as protection from corrosion caused by aggressive acid mist. This method of protecting the anode bar also ensures the best possible bond between lead and copper for improved current flow and long service life.

 

The anode plate is welded to the homogeneous lead-coated copper bar by means of a two-sided lead corner seam (1), or welded to an integrally cast lug (2). Alternatively, the anode plate can be inserted in the dip-leaded rod (3). Another possibility consists of electrolytic lead-coating of the copper rod (4).
