Four Easy Tips to Capture Added Revenue From Your Precious Metal Refining

Journal ‘ Endorsed Programs News’ November 2016 issue

Dentists may routinely collect failed crowns and bridges for precious metal refining. But there are other less known income opportunities in precious metal refining you may have overlooked.

Bench lemels and grindings

Trimmed work from crown construction represents the highest return of all lab waste. These grindings and other high-value material such as casting machine flashings are melted down to form a bar.

Extractor bags

Floor sweeps are the residual dust and off cuts accumulated on the floor around the work bench. Usually collected into extractor bags, these generate high volumes of low grade material which are incinerated to a fine powder, milled into a homogeneous material from which any precious metals are recovered. Floor sweeps reclamation is one of the major revenue opportunities available to a dental practice.

Platinum and palladium foils

Most of these items are pure 99.9 percent and are tested and purchased without need for processing. Palladium is at the present used more regularly in dental restorations as it is a less expensive metal than gold and considerably cheaper than other platinum group metals.


Fibers of a carpet in a dental practice can capture significant value. If the vacuum has been run over the carpet then it is likely that the value would be in bags if retained. In 2006 (even when prices were much lower) one carpet that had been down for 20 years yielded over $22,000.

There are many alternatives for precious metal refining. The MDA has done the legwork for you and endorses D-MMEX EasyRefine for precious scrap metal refining. MDA members receive an added 5 percent premium on the total value of the submission. Current rates are 97 percent for gold, 90 percent for platinum and silver and 85 percent for palladium.
