THE REFINING PROCESS
On receiving the metal at the refinery, it is weighed, coded and sent for Homogenisation where it is melted in induction furnaces to make a homogenous alloy, after which samples are drawn. Customers are welcome to witness the melting and sampling of their material, The melting facility is equipped for surveillance & has other amenities that help in recording the transparent processing of your precious metals.
We employ various refining methods depending on the precious metal content of the metal received, starting from Inquartation for low-grade alloys, Aqua-regia for alloys bearing 80% gold content & Electrolytic refining for obtaining 999.9% pure gold.
