Dear Isheunopa Mureyi sorry to see that your interesting and important technical question has not yet received any expert answers. In such cases I made the experience that it often pays off to directly search the "Publications" section of RG to find and access helpful research articles about a certain topic. You will be surprised to see how many useful paper have been posted by RG members, many of them even as public full texts such as the following articles:

Fundamental principles of froth flotation

Article Fundamental principles of froth flotation

and

Froth flotation process and its application

Article Froth flotation process and its application

Both articles can be freely downloaded as pdf files. Also please have a look at the following useful articles which deals particularly with the platinum group metals (PGM):

Challenges Related to the Processing of Fines in the Recovery of Platinum Group Minerals (PGMs)

This paper has been published Open Access and is thus freely available as full text on the internet (please see attached pdf file).

I hope this helps. Good luck with your research and best wishes, Frank Edelmann

Dear Isheunopa

For better understanding the flotation, take a look at the following references:

- "Surface Chemistry of Froth Flotation", by Jan Leja

- "Handbook of Flotation Reagents: Chemistry, Theory and Practice" by Srdjan M. Bulatovic.

Best of luck
