The mineral to be collected or the gangue material in case of reverse flotation.

Alireza Mirhosseini-Jalalabadi

thanks, but your answer is very basic.

The answer is basic because the question was. You did not give any details to warrant a more specific answer.

Yes, you are right. Do changes in zeta potential and pH play a role in choosing collectors?

I have to think about that, I believe so.

Thanks for posting the article.

In general, it seems to me that as the zeta potential becomes negative, the surface charge of the mineral becomes negative. what do you think?
