Our precious metal refinery FAQs page is designed to answer some common questions and point you in the right direction when considering recycling your precious metal scrap.

A precious metal refinery recycles scrap precious metals from various sources by collecting, assaying, and refining metals back to their pure form. Core Scientific specializes in refining scrap metals from the platinum group (Gold, Silver, Platinum, & Palladium) from jewelry, items from pawn shops, and dental scrap.

When we talk about dental scrap, we are referring to scrap metal that contains precious metals that can be recycled and refined. Dental scrap metal recycling is a great way to generate passive revenue and help the environment!

For a quick definition, when we talk about selling dental scrap, we are talking about selling dental scrap metals. Dental scrap includes:

  • Gold, silver, platinum, or palladium from crowns, caps, or bridges
  • Porcelain fused to metal (PFMs)
  • Porcelain fused to gold (PFGs)
  • Fillings
  • Inlays and Onlays

Every bit of gold we receive is made up of different metals that result in the gold’s purity. Purity is measured in karats which represents how much pure gold is in the metal. Gold is used for many different applications so other metals are typically blended with the gold to give it different properties for its intended use. Gold typically is measured in 12, 14, 18, and 24 Karats which ultimately reflects how valuable the gold is per Troy Ounce. Core Scientific takes the weight of gold metal itself and uses the London PM Fix Market Price for gold to determine the price or value. So, it depends on the weight of pure gold found and the market price of gold when it is refined.

Since other precious metals are commonly used in dental gold, Core Scientific also isolates these metals and uses their weights and market prices to give you the full value of your material.

In order to get the exact value of your precious metal, it must be refined and assayed by a professional. However, if you want to get an idea of how much value you could be sitting on with your precious metal scrap, we suggest using our Karat Calculator to estimate the price. The calculator uses current market prices to determine your gold’s value. All you need to enter is a weight. A flat weight might over estimate the value of your gold but if you know what karat your gold is, you can determine the percentage of the gold in the total weight and get a much more accurate price.

As we’ve mentioned, Core Scientific refines precious, platinum group metals (highest value) along with some less valuable base metals like cobalt, titanium, and iron. However there are some materials that we are frequently asked to refine that we do not accept. We refrain from accepting:

Core Scientific issues a settlement once the metals are refined. The settlement details what metals were found, their weights, and the final values. We then mail a check for the full settlement value directly to you. We also offer payment in bullion which ensures you retain investment abilities of owning precious metal.

We do not offer payment in cash for dental scrap. Cash buyers typically offer a flat rate for a lot of dental scrap metal by guessing the value. Since they haven’t melted and assayed the material, they leave a lot of value on the table to make sure they make a profit. They then send the material to get refined to make their cut of the transaction.

Since Core Scientific refines each and every bit of scrap you send us, we are able to offer more for your material because we know exactly how much it is worth. Learn more about skipping the middleman here.

Once we receive your material at the refinery, it typically takes us 2-3 days to weigh and refine your metals, issue an assay report, and send your payment in the mail.

Core Scientific’s Customer Portal gives you 24/7 access to information about your material. View pictures, verify weights, download your settlement report, and follow the process to completion.

No! Core Scientific has representatives all over the U.S and Canada that are able to do local pick-ups. Also, our customers never pay for shipping. We will send collection containers with return shipping labels so you are able to consistently recycle your precious metal scrap and collect your settlements. We also make it easy to request a container here.

The alternative to recycling precious metal is mining it from the ore in the ground. This has many environmental and social impacts due to the large-scale operational processes used to extract the metals from the earth. Find out more about How Gold Refineries Decrease The Carbon Footprint.

Some of the impacts of mining gold include:

  • Large amounts of carbon emissions from equipment, ventilation systems, and deforestation.
  • Contamination from the use of Mercury in the extraction process.
  • Social impacts to the displaced communities around mining sites.

Recycling gold and other precious metals keeps them out of the piled-up landfills where they are lost forever.
