How fo you turn gallium oxide back into gallium?

Hiw do you separate it from carbon or from indium?

From wikipedia, "Ga2O3 is an intermediate in the purification of gallium."

So we'd turn the gallium oxide back into gallium the same way we did in the first place, when we made the gallium. I'm guessing we can also come up with chemical reactions for the other two.

However, you're right that gallium production is quite low. It's a byproduct of zinc production from bauxite, and we get only a few hundred tons per year. Wikipedia doesn't say what the potential might be if we gallium were the main product.

You would still need to spend a lot of energy for the process, which brings us to the beginning. This could maybe be used when we have fully renewable enegry in excess to pull some carbon out of atmosphere.

Can we do it while it's still mixed with indium?

Is gallium oxide dissolved in EGaIn?
