Minerals Technologies Inc.

A global specialty minerals company that digs up and transforms minerals like bentonite and calcium carbonate into everyday products — from clumping cat litter to paper coatings and construction sealants. It began in 1992 as a spin-off from the drugmaker Pfizer, which had quietly built a minerals division decades earlier. Bentonite, its signature clay formed from ancient volcanic ash, is sometimes called the "mineral of 1,000 uses."
