We Care. Clean Air, Pure Recovery

Precious Metal Refining

Our processes result in zero discharge, emissions-free, efficient and “clean” recovery, along with quicker turnaround.

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.

A Better Approach To Metal Refinement

The list of refining and recovery materials we process is extensive and comprehensive. We are able to refine both high and low grade materials that contain precious metals.

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.
