SILVERTIP offers you melting and refining services.
Below are pictures of our process, and the final product. We produce beautiful looking bars, if you're looking to have all your gold combined in one easy to store bar / brick.
In this case, we started out with Placer Gold, mixed with many impurities. We need to extract the impurities and seperate the gold into a shinny new bar.
Mixed with fluxes, etc., the product is first melted and poured into Cronical molds. These pyramid shaped molds help bring as much impurities to the top as possible. The result is low grade gold buttons that still contain an unaceptable level of impurities.
After melting the buttons several more times, and removing the slag each time, we gradually produce higher quality bars.
Each time, more impurities are removed, as they attach themselves to the flux. This layer is thensmashed off, leaving the higher grade gold behind.
Several pours later, very little impurities remain.
Doing the final melt
After cooling, cleaning, polishing, buffing by hand and with power tools, the gold is submersed in the ultrasonic machine for 30 minutes..... producing the final product.
A beautiful poured bar of precious Gold !
