With dry processing, the entire stone, including the impurities, is ground into product. Wet processing, in contrast, offers the opportunity to improve the purity of the products by a reverse froth flotation process. The reverse flotation process removes the impurities, usually highly colored, from the carbonate ore as a froth.

Mohs hardness will scratch or abrade a material with a lower number. Calcium carbonate is a soft mineral with a Mohs of 3. Since ground calcium carbonate is a naturally mined material, impurities exist in all ore bodies. Almost all contain some dolomite (CaMg(CO 3) 2) with a Mohs of 4, while others contain mica (Mohs 3) or graphite (Mohs 1-2).
