Specialty Minerals

Precipitated calcium carbonates (PCCs) make your paper white, your vinyl windows and siding tough, and your bones strong. Talcs protect your car bumpers from damage and your house paints from weathering. Ground calcium carbonates (GCCs) make stuccos bright, roof shingles durable, and chewing gums chewy. PCCs and GCCs come from the mines and processing plants of Specialty Minerals Inc. (SMI). Talc comes from the mines and processing plant of Barretts Minerals Inc. (BMI).

On this site, you’ll find information on talc, limestone and PCC. You’ll learn what they are, where and how they are used, and their contributions to the performance of our customers’ products. Included are guidelines to help you choose the right product for a particular application.
