In 2011, Imerys Minerals and Norsk Minerals merged their key production plants—Spruce Pines, North Carolina, and Drag, Norway—to form The Quartz Corp (TQC). This 50/50 joint venture, capitalising on the expertise of both companies, and Imerys’ access to the world's purest quartz deposit, has enabled The Quartz Corp to supply top quality High Purity Quartz to customers within a variety of industries. With offices in North America and Europe, as well as employees on the ground in China, we are able to support a network of global customers, many of whom are key players within their respective industries. Our vision is to become a major and sustainable player in the High Purity Quartz market by supplying High Purity Quartz materials to all relevant market segments. Our High Purity Quartz is unique, sourced from Spruce Pines, the only mine on earth with quartz pure enough to produce the crucibles needed to manufacture semiconductor ingots. Taking this unique product from Spruce Pines, combining this with our other pure quartz source in Drag, Norway, treating it in our plant in Drag, allows us to produce both standardised and specialised products for our customers, based on their needs. Working closely with customers and strategic partners, we strive to be the highest quality and most reliable producer of High Purity Quartz materials, providing solutions to our customers' evolving needs.
