Zerkleinerung • Comminution - Mineral Processing

The resulting high-frequency, high-velocity impacts cause a highly turbulent particle flow and trigger fracture nucleation and fracture propagation preferentially at and along mineral boundaries. Breakage occurs from the high-velocity stimulation of particles, where the elasticity and compressibility modules control differential particle behaviour.

Copper extraction - Wikipedia

The slag and the matte form distinct layers that can be removed from the furnace as separate streams. The slag layer is periodically allowed to flow through a hole in the wall of the furnace above the height of the matte layer. The matte is removed by draining it through a hole into ladles for it to be carried by crane to the converters.
