Tin Drag-Out Recovery

Does anyone have practical experience with RO or Vacuum Evaporation for Tin MSA dragout recovery?

I wouldn't recommend RO for a tin rinse because of the tendency for tin to oxidize and to precipitate as it is concentrated.

Vacuum evaporation would be a much better choice. I have some successful experience with fluoborate tin and tin-lead recovery using vacuum evaporation, but you must be sure that the addition agents are stabile at the temperature in your evaporator.
