As the largest global full-service refiner of precious metals, our services, technologies and refineries represent the most comprehensive and advanced precious metal refining facilities in the world.
As such, Johnson Matthey is able to process precious metal materials from other refiners including reverted processed residues. In addition we refine upgraded residues and bullion from semi-refiners. Materials from precious metal collectors and semi-processors can also be refined at Johnson Matthey.
Precious metal concentrates from PGM miners as well by-product residues from base metals refiners are also refined by Johnson Matthey.
