Hi to all,

Currently we have taken a project on removing impurities by oxygen blowing and oxidizing flux addition to oxidize the base metals.

Need suggestions and clarification about this process like

1. Flux need to use
2. Flux ratios and flux calculation
3. Any other things needed to achieve better results in this trial.
 
I think there were a discussion a few days ago about this. When doing a quick search I found this one.

But I think there should be a more recent thread.

Thanks for your suggestions.

But still no one specified that the amount of oxidizing flux need to convert particular material into its desired oxide.

Is any calculations for the flux addition?
 
Sure.


NaNO3 + M(0) = MxOy + Na2O + NO2

put in your metal and balance the redox reaction yourself.

Note, depending on the metal, there may be secondary reactions with the sodium oxide.
