Filling the gaps with Nordkalk C-series

Nordkalk C-Series products are micronised calcium carbonate products (CaCO3) that are manufactured from high-quality calcite marble. The process involves removing impurities from the calcite using optical separation and foam flotation. The enriched calcite is dried and ground to the desired particle size in an enclosed fine grinding circuit. All of Nordkalk's C-Series products are manufactured in Lappeenranta Finland and their special characteristic is a high degree of whiteness.
