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.
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.

M&K’s chemical refining process is ideally suited for the cleaning of deposition equipment and the reclamation of precious metals used in PVD processes. Our chemical cleaning process is gentler on tooling than bead blasting which can pit or warp shields thus shortening the life span of a shield kit. In conjunction with our service partner, we also offer surface treatment and coating as well as Class 100 parts cleaning and packaging for direct installation into customers' coating chambers.
