Dental labs
We deal with dental labs throughout the U.K. We can process and purchase your precious metal scrap in many forms including bench lemel and grindings, extractor bags, carpeting and platinum/palladium foils.
bench lemel and grindings
The filings and dust caught on on your worktop typically have a very high precious metal content. This is typically brushed and put into a lemel pot and should always be kept separate from your low grade sweep.
Extractor bags
Floor sweepings and suction dust are processed differently to the above due to the higher volume of material. Incineration is performed initially to break the material down. The resulting “ash” will then be placed into a ball mill to break it down into a fine homogenous powder. Numerous samples are then taken and assayed to ascertain the precious metal content and value.
