Extraction of tin from sodium stannate by electrowinning
Thread Content
For the electrowinning of tin from sodium stannate, what anodes and cathodes should be used, what additives must be added, and what electrolytic conditions need to be controlled? ?
Tin is used for the positive electrode, while an inert electrode such as a carbon rod should be used for the negative electrode. As for the specific process conditions, they haven’t been tried, so I wouldn’t dare to make any claims.
It seems like the guy upstairs is even less knowledgeable than I am, but thanks anyway for your support. Let’s take a look at what the experienced experts have to say!
For the extraction of tin from sodium stannate by electrowinning, use graphite as the anode and stainless steel as the cathode; heat it to 70 degrees and add some gelatin, and that’s sufficient
Question: What are the requirements for the anode regarding graphite?
Ordinary graphite used for electroplating will do; it might shed debris, but covering it with a filter bag will solve that problem
