Robin Kolvenbach, co-CEO of Argor-Heraeus. “For years, we have been working to increase transparency in the gold business with the help of new technologies and innovations. In addition to AI, we also use DNA tags and PCR tests for traceability from mine to refinery.”
In addition to AI, Argor-Heraeus has been working with DNA PCR tests since 2019 to increase traceability of gold. The DNA tagging technology used in this process comes from the Swiss startup Haelixa.
Argor-Heraeus tags raw gold bars at the mine with a DNA tag. Upon arrival at the refinery, these tags can be verified through PCR testing. Each mine has its own DNA tag, which is only accessible from the specific mine. Once the origin is confirmed, the bars are further processed in separate production lines. This helps avoid mixing gold from different origins within the refinery. With these separate production processes, Argor-Heraeus ensures that products can be traced back to their source even after smelting and that they comply with global regulations on the origin of gold.
