Unimin Corporation was a major North American producer of non-metallic industrial minerals, specializing in high-purity quartz, feldspar, nepheline syenite, olivine, calcium carbonate, and clay. Founded in 1970, and for many years a subsidiary of the Sibelco Group, Unimin supplied raw materials critical to various industries including glass, ceramics, construction, paints, plastics, and oil and gas. In June 2018, Unimin combined with Fairmount Santrol in a merger of equals to form Covia Holdings Corporation, a comprehensive provider of mineral-based and material solutions. This information reflects Unimin as an entity prior to this significant corporate change.
Served as the primary corporate office, overseeing strategic direction, financial management, sales, marketing, and administrative functions for Unimin's extensive mining and processing operations across North America and internationally before its merger into Covia.
The New Canaan office was a corporate facility; specific unique architectural highlights or extensive campus features were not widely publicized. It likely housed standard corporate amenities.
As a key player in the industrial minerals sector, Unimin likely fostered a work culture emphasizing operational excellence, safety, product quality, and innovation in material science. Being part of the global Sibelco group would have also influenced its corporate culture with international standards and practices.
The headquarters was significant as the decision-making center for one of North America's largest industrial mineral suppliers, influencing supply chains for numerous critical industries. It directed the company's growth, acquisitions, and operational strategies.
Prior to its 2018 merger, Unimin Corporation had a significant presence, primarily concentrated in North America (United States, Canada, and Mexico), with numerous mining operations, processing plants, and distribution facilities. As part of the Sibelco Group, it also benefited from a global network and expertise, though Unimin itself was focused on the Americas. Its products were supplied to customers globally, particularly its high-purity quartz and other specialty minerals.
