CALCIUM CARBONATE

M. BLEECK, Columbia River Carbonates

Calcium carbonate (CaCO3) is one of the most ubiquitous and versatile minerals. Its availability, attractive physical properties and low processing costs make calcium carbonate the most widely used filler material in today's industry.

It is estimated that the United States currently consumes about 3.6 to 4.1 Mt/a (3.9 to 4.5 million stpy) of calcium carbonate. It is mined in three different forms - chalk, limestone and marble -- throughout the world. Each physical form of calcium carbonate has distinctly different qualities due to ...
