The effect of conditioning on Froth Flotation

Most forms of conditioning for flotation were found to fit into two basic categories, which if they both take place in the same process, follow one another sequentially. In this thesis, these were termed "primary" and "secondary" conditioning, and were defined as follows: Primary Conditioning relates to the physical preparation of the surJace ...
