- Lead anodes are used in SX-EW ( Solvent Extraction Electro winning ) plants of Copper,Nickel,Cobalt,Zinc and Mangnese.
- Lead is alloyed with metals like tin,antimony,silver,calcium etc for various solvent solutions.
- Lead anodes for copper electrowinning – Lead Tin Calcium alloy anode.
- Lead anodes for Zinc electrowinning – Lead Silver alloy anode.
- Lead anodes for Mangnese Electrowinning – Lead Silver alloy anode.
Manufacturing Outlook :
- Anode plate for copper electrowinning industry is cold rolled lead alloy anode sheet with uniform grain structure, high corrosion resistance etc.
- This anode plate(lead alloy anode sheet)connects with the Copper hanger bar double-side welding with Lead alloy coating, or plate plug-in welding.
- The copper bar is coated with tin and then lead coated.
- The good welding technique and good quality anode plate and hanger bar allows the anode plate could use in harsh environment for long time.
Rolling of anode plate :
Cold rolling of anodes subsequent to casting improves the efficiency and life of the anode by separating the grain structure and stretching and orientating the grains for a more homogenous microstructure. This improves the anodes performance through:
Uniform conditioning and corrosion resistant
Opposition against creep
Further developed conductivity
Reduced porosity
