of comminution operations through the application of the highpressure grinding rolls units on the fine crushing stage. Numerous investigation results prove that products of highpressure comminution contain more finer particles, while an unfavorable phenomenon of overgrinding is limited. HPGR units also guarantee a satisfactory degree of feed disin

Froth flotation is the followon operation, after comminution and classification, in the process of liberating and separating minerals by exploiting the differences in physical properties of the different minerals that make up an ore. Froth flotation is achieved when particles are separated based on their surface potential.

Froth flotation for beneficiation of printed circuit board comminution fines was investigated in this work, via reverse flotation under a scheme described as natural hydrophobic response. With no reagents, the scheme employed variation of kinetic parameters of airflow rate and impeller speed to optimize metallic enrichment of the sink.
