Material solutions: fit for purpose, delivered on time and in-specification

Unimin Corporation is an application-focused company drawing from a diversified product portfolio and the worldwide production capabilities of Sibelco, our privately held parent organization. We are the world’s largest producer of low-iron nepheline syenite used in glass, ceramic, paint and plastics, and the largest producer of quartz proppants for oil and natural gas stimulation and recovery. We are also the world’s leading producer of high purity quartz, a highly specialized product used in the fabrication of integrated circuits, solar photovoltaic cells, and high-intensity lighting.

Unimin processing plants are situated on the continent’s best mineral deposits; each a multi-million dollar investment in chemical consistency, product uniformity and reliable supply. Regional offices, technical centers, and analytical laboratories are organized to support production and commercial activities and serve as customer resource centers.

Creating Value

Unimin maintains strong customer relationships by delivering quality, service and expert technical support. A fundamental strength of the Company is its application-focused technical centers and customer teams.

With hands-on industry experience, these teams help improve productivity, create a performance advantage or develop next-generation products in a wide range of customer applications.

To convert concepts into production realities, we operate one of the world’s largest industrial mineral research organizations. Marketing and product development teams draw upon the expertise of scientists and industry experts to optimize functionality, performance, and value. Committed to both basic and applied research, this group has pioneered new and proprietary technologies that make it possible for Unimin to convert natural resources into engineered mineral solutions.

Our Philosophy

Unimin is managed with a long-term perspective. We invest for the future and manage for the next decade, with emphasis on growth, diversification and sustainable development.

Our business model is built upon the strategic alignment of superior and extensive mineral deposits, advanced production technologies and skilled and innovative people to deliver performance and value to our customers.

Perhaps more than any other business, mining, and mineral processing companies are defined by their corporate values and the policies and practices that govern daily operations. We’re committed to the principles of sustainability and the responsible development of resources to fulfill today’s needs without compromising the needs and requirements of future generations.
