We Care... Clean Air: Pure Recovery

Ownership delivers on over three decades of refining expertise.
M&K distinguishes itself with the use of a chemical-based refining process that maximizes the recovery of precious metal scrap materials. Our state-of-the-art North Andover, MA headquarters is certified by a Massachusetts DEP B4 Level III Hazardous Waste Recycling Permit. “Green” chemical processing of gold, silver, and platinum group metals is recovered from encapsulated, clad, and plated material. A cyanide strip method is employed for gold-plated scrap products, with recovery and treatment of solutions also performed. Our processes result in zero discharge, emissions-free, efficient and “clean” recovery, along with quicker turnaround.

Refining Materials

• Gold-plated scrap: Circuit boards, PGA, BGA, IC’s, connectors, plugs and pins
• Gold, PGM’s from: Bell jar and deposition scrapings, Flake, Sand, Bead blast
• Scrap IC packages, hybrid circuits
• Used / Spent targets
• Pt thermal couples and refractory waste
• Rejected silicon or gallium wafers
• Mylar (blue tape) “lift-off,” transfer or skeletons
• Precious metal bearing pre-forms or cut-outs
• Filters, resin columns and salts
• Thick and thin film residue, including conductive pastes, rags and wipes
• Recovery / Treatment from spent or contaminated gold and platinum solutions
  

Assay Services

M&K offers sample analysis to determine values of homogenous categories of material. Assay is achieved via atomic absorption spectrometry, x-ray, or fire assay. Analyzing sample material allows us to report values to our customers—and if approved, an outright purchase schedule of the material will be provided.
