Imerys is a French industrial group headquartered in Paris and listed on Euronext Paris. Its roots go back to 1880 with the creation of Société Le Nickel, and to the Imétal holding formed in 1970 by the merger of Peñarroya, Le Nickel and Mokta. In the late 1990s Imétal refocused on industrial minerals and bought the British company English China Clays in 1999.
On 22 September 1999 Imétal was renamed Imerys. The group then grew through acquisitions (World Minerals, Luzenac, S&B, Kerneos and others) and produces kaolin, calcium carbonate, talc, graphite and andalusite, among other minerals. In 2022 it announced a lithium mining project in the Allier department.
In offshore racing, Imerys is the title sponsor of the Class40 skippered by Britain's Phil Sharp, which raced as Imerys and then Imerys Clean Energy from 2016 to 2019, according to the boat's fiche.
