What is Assaying?
Assaying is the process of analyzing a metal to determine its content and quality. This critical service ensures that the metal’s composition meets industry standards and client specifications.
Our Assaying Processes
A small sample of gold is taken from a larger batch. This sample must represent the whole batch accurately.
The most common method, involving several steps:
* Fusion: The sample is mixed with lead oxide, litharge, and other fluxes and then heated. Lead acts as a collector for precious metals.
* Cupellation: The molten lead containing the gold is poured into a porous cupel and heated. Lead oxidizes and is absorbed by the cupel, leaving behind a bead of gold and silver.
* Parting: The bead is treated with nitric acid to dissolve silver, leaving pure gold.
The remaining gold is weighed, and its purity is calculated based on the initial sample weight.
