PAMP SA (Produits Artistiques Métaux Précieux) is an independently operated precious metals refining and fabricating company and member of the MKS Group. It was established in 1977 in Ticino, Switzerland.

Originally starting as a minting facility of bars weighing less than 100 grams, and as an alloy specialist for the jewellery and luxury watch-making industries, it has grown to provide services from collection of doré from the mine, through to assaying, hedging and delivery of its bars and other products. The company produces bullion bars, from 1 gram to 12.5 kilograms.

PAMP also provides custom minting service for private companies and government mints. The company's product range in that field goes from small bars and medals to legal tender coins.

Umicore N.V.. formerly Union Minière, is a multinational materials technology company headquartered in Brussels, Belgium.

Formed in 1989 by the merger of four companies in the mining and smelting industries, Umicore has since reshaped itself into a more technology-focused business encompassing such areas as the refining and recycling of precious metals and the manufacture of specialised products from precious metals, cobalt, germanium, zinc, and other metals. The company has been a component of Belgium's benchmark BEL20 stock market index since its 1991 inception.

To symbolise this trend of moving away from mining and the production of commodities and base metals, the group Union Minière changed its name to Umicore in 2001.
