The Refining Process
Gold Stock's Refining Division is fully transparent, allowing you to see our well-trained refiners take care of everything in front of you. We are able to meet the needs of your melt, such as going through the process step-by-step before beginning.
The first step of our refining process involves weighing in jewelry and/or scrap bars. This step allows us to distinguish between what is alloy or magnetic. The recorded weight helps us to analyze how much of a difference in loss of weight can occur. These are examples of weight imbalances:
- Low-Karat below 15%
The melting process. Here the gold/silver is melted in our induction furnace heating generator to melt the gold or silver into liquid. Borax powder is added to ensure better results and higher gold/silver yield and to remove impurities. During the process, stirring of the liquid ensures the stability of the karat purity, producing a homogeneous bar.
Outcomes a "dore bar" of scrap gold or silver, which is then weighed after to indicate the exact loss of weight from the melt. This will be the actual weight of gold/silver content. As a note, there will always be a melt loss due to any stones or diamonds that is attached to jewelry. Stones will not melt. We kindly advice to remove any stones that you can as this will guarantee accurate results when determining the actual melt loss difference. We offer a stone removal service for these circumstances.
The scrap bar's surface is sampled and tested under our X-ray fluorescence machine ( X-Strata & Spectro-Midex ). This laser technology will accurately display all alloy contents in percentages in 90 seconds.
The final step is your pay-out. We rely on Thompson Reuters's precious metals market data for our gold, silver, platinum and palladium rates. You have multiple options in, cash, cheque, wire,
This is how we dictate our charges.
