Assay Services

Umicore uses the following state of the art assaying technologies:

Fire assay: the most suitable method for the determination of gold and silver and the standard for commercial transactions in the precious metals industry. In order to benchmark our laboratory, we participate in ASTM round robin tests every six months.
Classical wet chemistry: although labour and time intensive, these methods provide the most accurate results for complex materials.
ICP-OES: a proven technique to determine impurities in precious metals materials.
X-ray fluorescence spectroscopy: a semi quantitative, quick analysis of a material’s composition.

Our Management system conforms to ISO 9001, ISO 14001 & OHSAS 18001
