Argor-Heraeus traces its origins to 1951, when it was established in Chiasso, Switzerland, under the name Argor SA. From its inception, the company focused on refining precious metals, quickly gaining a reputation for excellence in the production of gold, silver, platinum, and palladium of the highest purity. Its Swiss heritage became synonymous with precision and integrity, and over the following decades, Argor evolved into one of Europe’s most respected refineries, supplying both investment and industrial markets worldwide.

In 1986, Argor entered into a strategic partnership with Germany’s Heraeus Group—an internationally renowned leader in technology and precious-metals processing—forming Argor-Heraeus SA. This collaboration combined Swiss refining expertise with German technological innovation, solidifying the company’s global standing. Heraeus Group eventually assumed full ownership in 2017, integrating Argor-Heraeus into its global network. Today, Argor-Heraeus operates as one of the world’s foremost precious-metal refiners, recognised for its unwavering commitment to quality, sustainability, and responsible sourcing across international bullion and jewellery markets.
