Smelting and Metal Scraping

We specialise in the traditional Fire Assay Method, also known as the Cupellation Method, to determine the concentration of Gold. The technique uses Titration and Inductive Coupled Plasma or ICP to determine the purity of metals with very high precision.

X-ray Fluorescence is used to determine the elements present inside the alloys. ICP is also used to verify the purity of scrap gold that cannot be detected by fire assay due to the influence of contamination group elements. It is also used to cross-check the final product and results to determine the chemical concentration and company waste chemical specifications for disposal or reuse.
