Amethyst crystals or other intergrown gemstones can largely be liberated from the crystal composite without damage.

Concrete is a typical composite material comprising gravel, sand and cement stone. Concrete structures have limited lifetimes and they constantly need to be renewed, creating many millions of tonnes of used concrete each year throughout the world.

High-quality, high-yield indicator minerals can easily be liberated from kimberlite samples.

Waste from the electronic and automobile industries includes

composite materials containing valuable substances that are often
difficult to liberate with mechanical comminution methods on
account of their complex structure.

selFrag Lab is perfectly suited for the selective fragmentation of mineralogical and geological samples as well as composite materials in the range of a few kilograms. It offers the possibility of selectively liberating target specimens while minimizing the by-production of fines.

Metallic smelting slag from copper and stainless steel production, or slag from waste incinerators, often contains significant percentages of pure metals in the fine-grain range which are often impossible to recover cost-effectively with classical methods.

Selective fragmentation with selFrag Technology makes it possible to liberate high-purity quartz crystals from composite rock largely without contamination and with low loss of undersize particles. The expected yield is significantly higher than for mechanical comminution processes, and the degree of downstream processing is substantially lower.

The selFrag Glass plant makes it possible to preserve value by recycling high-purity quartz or speciality glass.
