➀ The Fraunhofer Institute for Integrated Circuits IIS has developed a patented method with GEM Recovery Systems GRS to analyze antimony particles in rock using modern sensor technology. This allows for the identification of rare earths and minerals in rock and separation from worthless materials, increasing independence on this critical raw material. ➁ Antimony is a key component in many products, including semiconductor technology, solder, and car batteries. China and Russia are major suppliers, but China is imposing export restrictions on the rare material. ➂ The researchers are developing a sensor-based sorting technology to identify the metal in mining operations. This new technology could significantly reduce resource consumption and investment costs in the mining industry.
