We use a wet chemical process to recycle scrap metal back to pure form. The metals are dissolved in an aqua regia solution; from which we selectively precipitate each element of interest. Further processing is then required to remove trace elements before the precious metal is used in our line of dental product.
Once the scrap job is settled it is placed in a refining lot and moves through our batch refining process.
The first step of the refining is to flake the refining lot in water to increase the surfaced area.
The flaked gold alloy is then dissolved in aqua regia, an acid solution containing the precious metal ions.
From here each element is selectively precipitated, then additional steps are taken to purify the metal before it is used in our line of casting gold and palladium alloys.
