Excessive foaming in metallic ore flotation (2 replies)

I am working on a high clay content metallic ore flotation. Although I did not add froather, from the moment I turn on the air, excessive foam is formed and the product overflows from the cell.
The reagents I used in the tests are KAX, Na2S, CuSO4 and Na2SiO3 to depress silica.
How can I stabilize this excess foam?

Your main issue is probably the clay, since clay can be any one or a combination of several minerals, only detailed testing can confirm what is actually causing your problem.  A drepessaant such as oxiflot may help, but again detailed labe testing is required.

Try to dilute (add water) your flotation feed as much as possible.
