Focus on Fine Gold
Due to recent events in our industry, some refiners are beginning to focus on fine gold and high karated gold sent in for processing. Until recently, the practice of accepting refined gold was widely accepted by many refiners. The issue arises when the end user or primary refiner is certified by an agency such as the EICC as only processing metals from conflict-free regions yet fail to properly verify or document the source(s) from which the fine gold was received.
United is proud to be certified by the EICC for only accepting conflict-free gold from properly verified sources. Every lot received in our refinery is scrutinized before being processed to ensure compliance with our certification requirements. Fine gold received and processed at United is only accepted from reputable and certified refiners like United that have passed the vigorous process of achieving certification from the EICC and/or SCS Global Services.
We realize that the immense amount of documentation required by United can at times seem overwhelming to our customers. However, it is imperative to our business model and the many global corporate customers we serve who insist on only purchasing 100% recycled gold and silver. We do not buy gold from mines, industrial or electronic sources. United is proud to serve the jewelry industry by recycling old jewelry and byproducts from manufacturers and making quality products from that refined material such as karated grain, master alloys, wire, solder, sheet, tube and conflict-free fine gold and fine silver grain and bars.
Many customers at United benefit from not only refining services, but also the purchase of products such as karated grain, solder, wire, tube and sheet as well as our analytical services. Because these customers utilize all three of United's branches – Refining, Products and Analytical – we are proud to introduce United Full-Circle.
For customers who take advantage of this program, United offers discounts on select products when purchased using refining material. If a customer were to purchase fine gold, they would pay a certain amount over spot based on the quantity being bought. However, if you were to send in a lot for refining, the fine gold that lot yielded would be returned to you with no additional charge other than the refining charges. Discounts are also available on the purchase of certain products such as solder and karated grain when purchased from refining. To learn more, please contact your account representative.
Color Changes on Rose Gold Alloys During Casting and Finishing
Rose Gold is becoming more popular. We occasionally get calls from customers with the complaint that their rose gold casting became very yellow after casting. Rose gold alloys have a very high copper content and some of the rose gold alloys will form a heavy black surface oxide during the casting process. To remove the surface oxides the rose gold is pickled after casting. The pickling process will remove the oxide and some of the copper on the surface of the casting, long pickle times will remove more copper on the surface and enrich the gold on the surface giving a yellow color.
Copper is soluble in most acid or "Sparex" pickle solutions but gold is not soluble. If the rose gold turns yellowish during pickling, it can be restored to the red color with finishing with an aggressive polishing compound. The enrichment of gold on the surface of the casting in known as Depletion Guilding, in the case of rose gold it is not desirable.
