Selective comminution of two component mineral mixtures

1. The main criterion which determines the effectiveness of selective comminution is the ratio between the energy of the grinding bodies and the energy required to break particles of the weak component of maximum size, and particles of the strong component of the minimum size. The maximum effectiveness of selective comminution is achieved in cases of operating with energy combinations (3), (11 ...
