Our Lompoc, CA operation is the biggest working diatomite mine on the planet. The state-of-the-art, dedicated diatomaceous earth (DE) facility at Lompoc produces high-purity filter aids for the biopharmaceutical and pharmaceutical industries, including blood fractionation, that have become benchmarks worldwide. DE products from Fernley (NV) and Quincy (WA) are popular for the filtration of beverages and industrial liquids, and are used in paints and as mechanical insecticides.
Our Sylacauga operation (AL) is home to the world’s largest calcium carbonate open-pit mine. Along with our Marble Hill (GA) and Whitestone (GA) operations, Sylacauga supplies ground calcium carbonates for food fortification and to enhance the performance of paints, plastics and rubber - amongst others.
Our 9 perlite facilities - which include expanded perlite and cryogenic insulation production units - produce sophisticated solutions for use in agriculture, cosmetics, construction, beverage and industrial filtration, and horticulture, including such well known brands as CynerSorb and Harborlite.
Kaolins from our Langley (SC) and Sandersville (GA) operations boost product performance and processing in a host of end applications ranging from ceramics to plastics, rubber to adhesives.
Rare ball clays from our Crenshaw (MS) and Gleason (TN) operations are highly valued ingredients in high-end sanitaryware and tableware.
Engineered wollastonites from Willsboro (NY) and micas from Kings Mountain (NC) are essential ingredients in lightweight automotive plastics and tires.
Benchmark solutions for the refractories, advanced ceramics, construction, infrastructure and metallurgy and industries
Our refractories, abrasives and construction operations serve the continent with specialty materials derived from our portfolio of andalusite, bauxite, calcium aluminate, fused alumina, mullite, fused silica and zirconia.
Our Andersonville (GA) ‘Mulcoa’ plant is the world’s largest producer of sintered mullites. They are produced from unique high-purity, refractory-grade kaolin clay from the South Georgia kaolin belt. The Mulcoa® brand name is renowned in the world of refractory alumino-silicate calcines as the benchmark for refractory production.
The Niagara Falls (NY) site has roots going back as far as 1917. Today, the facilities supply brown and white fused alumina and silicon carbides for use in a broad array of end products, such as abrasives, refractories, blasting media, investment casting and foundry applications.
Our Norfolk site on the Virginian coast specializes in the production of high-performance fused bauxite and limestone and sintered alumina and lime for use as cement, concrete and specialty binders in building, refractories, metallurgy, mining, tunneling and wastewater infrastructures. They are sold under some of our oldest and well-known brand names such as Secar®, Sewper®, Sewpercoat®, Ciment Fondu®, Fondu®, Peramin® Ternal® and Fondag®.
Our fused minerals operation at Greeneville, Tennessee, is the North American port of call for fused silica and zirconia specialty products. Fused zirconium oxide products from Greeneville are prized raw materials in refractories, technical ceramics, friction materials, ceramic membranes and foam filters and nuclear applications - and include our renowned Zionic® brand. Our fused silica grains and powders, derived from high-purity quartz, are designed for advanced ceramics, electronics, molded compound, refractory and investment casting applications.

Imerys exhibited and presented at this week’s UNITECR, a key technical conference for the refractory industry. Experts from the Group discussed new products, sustainability and how to support young professionals in the industry.
As it seeks to take on the challenges and opportunities of the future, Imerys needs partners in innovation with whom it can fully leverage the latest emerging and transformative research.
Calcium aluminate has been used in sewer environments since the 1940s. Initially, the drivers for its use included its resistance to sulfates in soil, rapid return to service and superior abrasion resistance.
The team's joint efforts brought recognition from the Center for Disease Control and Prevention (CDC).
