Dental refineries, though they may have their own process of recycling dental scrap, follow the general concept of making sure that the dental work is left cleaned and still valuable. Here is a look at how scrap dental gold is turned into something worth of value.
- The dental scrap is weighed and characterized to take note of its initial qualities.
- To dissolve the metal into metal ions in a chloride solution, hydrometallurgical methods are used. Each metal is removed separated either as gold or as platinum and palladium. Using a selective precipitation method, they are able to effectively separate the components of the dental work to determine the precious metals. The weight of gold they find will help the refinery decide the value of your dental scraps.
- The refinery will send you a detailed report on the actual quantities of precious metals recovered.
