Contamination free Comminution

Electrodynamic comminution is an enhanced technology to liberate high purity quartz crystals from composite rock largely without contamination and with low loss of undersize particles.

A high-voltage discharge generates shock waves within the quartz lump causing fragmentation of the rock along crystal boundaries. Since crystal boundaries host most of the mineral impurities, downstream processing is more efficient and expected yield increases significantly compared with mechanical comminution techniques. Moreover, selective fragmentation technology is ideal to selective liberation of gas and fluid inclusion trails within the quartz crystals. All this makes electrodynamic comminution a favored method in high purity quartz processing.
