Frequently Asked Questions

What type of dental scraps do you accept for refining?

We refine any dental scraps such as Crowns, Bridges, Grindings, Sweepings, Vacuum filters, Carpets, etc.

Do you accept amalgams?

Unfortunately, No.

Do you accept other metal scraps such as Jewerly?
It depends on your scraps. Please email: dental@jrefining.com
What is the minimum amount of scraps you accept?

At lease 2 toz of scraps is recommended.

What fees do I pay for refining?

We will charge 1) Assay and Treatment charge of $80 per lot. 2) Refining charge for each metal of $35 per toz for Gold, $45 for Palladium and Platinum and $3.50 for Silver. We calculate your metal value by 97% of London Bullion Market Price.

How do you assay metal scraps?

Our assay procedure (wet method) is not the same as (dry method) other refineries use. Using the wet method, all the scraps are dissolved in acids, such as Hydrochloric acid and Nitric acid, then assayed by ICP and refined. It takes more time than the dry method. However, the wet method is more accurate than the dry method, because any samples from any point of dissolved metal shows the same assay results. On the other hand, the assaying by dry method is a little bit fluctuated and sometimes not accurate.”

How long does it take to make a payment?

It usually takes 4 weeks to complete assaying, then we arrange payment by check or wire transfer.

Can you return my dental scraps if I am not satisfied with your assay result?

We understand your concerns.  We would like to, but that is one thing we can not comply.  
As all of your dental scraps are dissolved in some kinds of acids, such as Nitric acid for assaying by our ICP to conduct an in-depth analysis and evaluation, we cannot return the scraps we received to you.

What is your advantages compared to other refineries?

We use the latest assaying technology and our refining cost is less than others because our partner refinery produces the final products such as gold and silver ingots and bars. Some refineries incinerate metal scraps and just sell them to other refineries who produce the final products.
