Unveiling the True Worth: Traditional & Cutting-Edge Techniques

Our expertise lies in the time-tested fire assay method, also known as cupellation. This technique meticulously separates gold from impurities, revealing its true essence.

But tradition meets innovation at Numbi. We utilize cutting-edge technology like:

Inductively Coupled Plasma (ICP)

This high-precision method precisely determines the purity of your metals, ensuring you get exactly what you deserve.

X-Ray Fluorescence (XRF)

This advanced technology acts like a metal scanner, identifying all the elements present within your gold or silver alloys.

ICP: The Double-Checker

For intricate scrap gold potentially contaminated, ICP comes to the rescue. It uncovers the hidden composition, ensuring no detail goes unnoticed.  Furthermore, ICP acts as a final verification tool for our products and waste materials, guaranteeing their chemical makeup meets the highest standards.
