The story

The company was first founded in 1880, when the Rothschild family combined some of their metals and mining interests into the Spanish company Peñarroya. Over the next century it specialized in extracting and processing non-ferrous metals, becoming one of the world leaders in mining extraction.

After operating as a stand-alone company, in 1970 Peñarroya branched out and merged with the Société Le Nickel (now Eramet) and Mokta (now Société Mokta El Hadid) and created a new holding company called Imétal to manage the new business.

By the end of the 1990s, the company had become entirely focused on industrial mineral processing, following more acquisitions and a few divestments. In 1999, Imétal changed its name to Imerys. The company continued to expand its product lines, geographic reach, and markets.

In 2018, the Imerys group sought to simplify its structure through a transformation plan, reorganising the company around two segments, and grouping five newly created business areas.

In October 2022, Imerys announced the commencement of a mining operation for a lithium deposit at Allier from 2027. A press release issued by the group specified that this exploitation of lithium should last at least 25 years and will constitute one of the largest deposits of the mineral in Europe.
