Because of the specific fragmentation mechanism, the shock-wave treatment, which induces fractures at the interfaces between different materials, the shock wave process is particularly suitable for processing mining products, and can also be used to break down rocks, minerals, and slags containing valuable materials. The specific separation mechanism of the shock wave technology is especially effective for processing minerals, since the material fractures tend to arise at the interfaces between materials with different acoustic properties. The fragmentation process is specific to each crystallographic (impurity) phase, which allows various microstructures to be efficiently broken down.

The method holds a significant amount of potential for treatment of valuable mining products and minerals. Shock wave fragmentation technology is able to recover and concentrate the valuable materials contained in rocks. This technology could potentially improve the efficiency of conventional processing methods in future. Over the last few years the shock wave fragmentation process extended to industrial scale. We are continually expanding the scale of the technology and developing customer-specific solutions in collaboration with an expert network of national and international partners from every field.

Advantages for applications

  • high selective fragmentation of multiphase systems
  • recovery and concentration of valuable materials
  • improved efficiency for subsequent chemical or hydrometallurgical processes
