The use of high brightness fillers is now necessary for most producers of any paper grade. The functional components like brightness, opacity, and smoothness are needed for printing, writing, and packaging grades.

Mineral fillers are also a vehicle to reduce the production cost of many paper grades. Since the mineral dries easier than fiber, steam demand is reduced and production increased. Replacing more expensive fibers with filler also reduces raw material costs. Depending on the grade, fillers can be used at levels from 1% to over 30%.

Columbia River Carbonates is currently one of the only manufacturers of cationically charged ground calcium carbonate fillers. This novel cationic grinding process yields a charge and narrow particle size distribution that allow for high retentions and excellent optical response.


The pigments used for paper coating bring brightness, a smooth printable surface and other functional properties to the final sheet. Columbia River Carbonates offers a range of particle size, surface area, and charge options to suit your needs.

Paper coatings today are applied in a variety of ways, all with different requirements for the pigment. From blade metering to roll coating to pigmented size press, Columbia River Carbonates has the products and expertise to help you achieve your goals.
