Recasting zinc anodes from zinc rounds

March 24, 2010

Our company has been thinking of recasting some of our zinc rounds into sheet zinc for a smaller rack plating bath.(we do not have suitable baskets to fit the tank) I am not so certain that that this is a good idea. Will the 99.99% pure anodes stay pure after heating and recasting them?

Hi,
The only way I can see it is if the anodes have too much of chloride gas inside in the zinc material, but if you clean them and heat them up then and melt again they will work as new anodes.

I used to make rods for internal anodes with cadmium from balls with no problems. Both have dangerous fumes, so be careful and use PPE.

Thank you for your answers. We have decided to make up a small test bath and try the recast anodes in it before using them in the rack bath. I will let you know how it turns out. Thanks again!
