Q. We have an accumulation of acid tin plating solution from dilution and de-sludging our production processes. Wondering if anyone knew of a method of either recovering the tin metal (some in solution and some as a precipitate) from this redundant solution.

We are located in Australia so any out-of-house solution to the problem would need to be local to us.

The solution contains around 25 g/ltr in 10% sulphuric acid solution but there is a lot of sludge as well some of which is almost spadeable due to evaporation of the liquid.

Any suggestions appreciated.

A. Bob,

Two simple methods have been used to recover tin

- Alkaline Precipitation.
- Electrolytic recovery on Stainless steel sheets.

Either method correctly set up can work for you.
