Mineral Liberation - an overview | ScienceDirect Topics

The concept of selective grinding recognizes that soft minerals have a slower grinding rate compared to brittle ones due to the effect that Tanaka [101], described it as the shielding effect [83,100]. The GAs increase the grinding rates of both minerals, which reduce the differences in the grinding rate [83,101].
