Umicore Precious Metals USA Inc
527 Pleasant Street, Building 11, Attleboro, Massachusetts, United States

Umicore provides gold, silver and platinum group fabricated products in a wide range of dimensions and shapes. Standard products include grain, wire, plate, strip, tube and ring blanks. These products can be made to our standard specifications or to match the requirements of various jewellery and industrial applications. Our ISO certifications give you additional assurance that we follow strict quality and environmental standards.

Refining Services

Refining of gold, silver, platinum and palladium has been an integral part of our North American operations for nearly a century. These services are provided to all facets of the precious metal industry, such as jewellery, dentistry, chemical and industrial sectors. Our operations are both ISO 9001 (quality) and ISO 14001 (environment) certified.

Gold Metallics

Bullion - dry, directly meltable metallics, containing less than 20% Ni and no Cd. Casting scrap (gates, sprues, buttons), bars, skeleton scrap, lathe scrap, flake, filings. Contacts on support blades, plates and posts can be processed provided the support is less than 50% of the total mass. Canadian gold coins are not accepted for refining.

Silver Metallics

Bullion - dry, directly meltable metallics, containing less than 20% Ni and no Cd, W or Fe. Casting scrap (gates, sprues, buttons), bars, skeleton scrap, lathe scrap, flake, filings. Contacts on support blades, plates and posts can be processed provided the support is less than 50% of the total mass. Canadian silver coins should be reported using the appropriate refining packing slip.

Platinum or Palladium Metallics (Including Dental Alloys)

Bullion - dry, directly meltable metallics, casting scrap (gates, sprues, buttons), bars, skeleton scrap, lathe scrap, flake, filings. Scrap from Dental offices without amalgam (mercury). Radioactive or bio-hazardous materials cannot be accepted.

Gold and Silver and Platinum Sweeps

Sweeps - dry, low grade residue from finishing or reclamation process with a particle size no bigger than a filing. Floor and bench sweeps, polishing dust, wheels, buffs, wipes, filters, carpets, crucibles, flux and or slag, requiring burning, grinding and sifting for processing into metallic dust prior to sampling and assay.

Gold Clad Products - Gold filled materials

Dry, directly meltable metallics with low gold content, less than 20% Ni and no Cd, W or Fe.

Car Catalysts

Car catalysts are recycled by Umicore. Please contact us for further assistance.

Recovery of precious stones

Recovery of precious stones from gold jewellery and refining of the gold. Recoverable stones are returned to the customer. Diamonds, cubic zirconium, rubies and emeralds are recoverable. Items such as onyx, tiger eyes, opals and pearls are not recoverable. Settlement times and costs may go up for items with rhodium plating, high silver content, PGM, channel sets etc.

Assay Services

Umicore uses the following state of the art assaying technologies:

Fire assay: the most suitable method for the determination of gold and silver and the standard for commercial transactions in the precious metals industry. In order to benchmark our laboratory, we participate in ASTM round robin tests every six months.
Classical wet chemistry: although labour and time intensive, these methods provide the most accurate results for complex materials.
ICP-OES: a proven technique to determine impurities in precious metals materials.
X-ray fluorescence spectroscopy: a semi quantitative, quick analysis of a material’s composition.

Our lab is ISO 9001 and ISO 14001 certified and strictly monitored for accurate results.
