How precious metals refining works
Gold Stock Corp. evaluates precious metal jewellery, scrap and other eligible material in stages. The exact steps depend on the form of the lot and the service agreed with our team. Contact us before bringing in or sending material so we can explain the assessment, charges and settlement terms that apply.
1. Intake and initial assessment
We record the material received and its weight, then review the lot for visible non-metal components, mixed materials and items requiring separate handling. Stones, solder, plating and other components can affect the relationship between the received weight and recoverable metal. Ask about stone removal and whether any items should be separated before processing.
2. Preparation and melting
Where melting is appropriate, the material is prepared and processed using equipment suited to the lot. A flux may be used to help manage oxides and other material during the melt. The resulting metal can be cast into a bar for weighing and further evaluation. Weight lost during processing does not by itself establish the quantity or purity of precious metal in the lot.
3. Sampling and assay
A representative sample may be tested to estimate metal content. X-ray fluorescence (XRF) examines the composition of the tested surface; results may not represent an entire mixed or plated lot. Fire assay may be appropriate where a more definitive analysis is required. The agreed sampling and assay method determines how the result is used in a quotation or settlement.
4. Quotation and settlement
After evaluation, our team explains the relevant weight, assay result, market reference, refining charges and proposed settlement terms. The amount payable depends on the metal recovered or assessed under the agreed terms, as well as the applicable market price and fees. Confirm the payment method and timing with our team before proceeding.
