Analytics – The Fire Assay

Noble Metal Refining utilizes a few techniques to quantify the purity of the Gold, Silver, Platinum and Palladium. The fire assay is the most widely accepted method to determine Gold and Silver content within the precious metal scrap industry.   Before a fire assay, Noble uses an XRF (X-Ray) analysis to get an idea of the basic composition of the material.  At Noble, we are purists, and manufacture 99.99% (.9999) Gold, Silver, Platinum, and Palladium on site. The XRF analysis helps guide the refining process to be certain that the proper smelting techniques are utilized. This captures the most amount of material for our clients and keeps Noble personnel safe at our facility.


Most refiners typically settle dental scrap and other Platinum group metals (PGMs) utilizing an XRF analysis.  Noble is one of the few refiners who utilize a chemical compound called Dimethylglyoxime (DMG) to assist in the analysis and purification of Palladium.

Noble Metal Refining settles out their clients with 99.99% accuracy on their metal.  Come watch for yourself!
