  Our Promise

All refiners will promise to pay the highest amount for dental scrap, but how will you know who's telling the truth? When researching how to sell your dental materials, observing the companies business structure will provide insight. If the company includes sales reps or brokers, this will raise their fixed costs. Raising the fixed costs will result in a lower payout for customers selling their dental scrap. Cora Refining eliminates all the Intermediaries creating a direct link between you and the dental refinery.

Providing immediate payment can not guarantee the highest payout. When companies provide 24 hour payment, you're likely to receive an estimate for what your materials are worth. Estimates will be lower, causing you to lose out on potential money you deserve. Cora Refining works to get you the highest possible payout for your materials. All of our prices paid and charges for recored metals can be found on our price schedule. We are up front with all charges,prices paid and settlement times to avoid any confusion.


From start to finish the security of your dental materials is our top priority. Every order is a 100% insured and shipped through FedEx.
