Ground Calcium Carbonate (GCC) is a natural, not a synthetic material. The characteristics of a GCC are primarily a function of its median particle size, particle size distribution and its impurities. Impurities can take the form of other minerals, metal salts, and metal oxides. The role of impurities is of special concern.

Groundwaters that are primarily controlled by carbonate reactions will have relatively high calcium and bicarbonate contents, and, if the rock includes some dolomite, could also have quite high magnesium levels. Data from a carbonate (karst) aquifer in the Mendip Hills (England) are shown on the following table and diagram. Characteristics

Ground Calcium Carbonate (GCC) or Limestone Limestone is a common sedimentary rock composed primarily of the calcium carbonate mineral, calcite (CaCO3). Limestone constitutes approximately 10 percent of the sedimentary rocks exposed on the earth’s surface. Either limestone or marble may be used as the basis for crushed or ground calcium carbonate.

CHEM 311: Environmental Chemical Analysis – Lab Manual Since the neutralization of calcium carbonate requires 2 mols of H+ as in Eqn {4}, the conversion from mass of CaCO3 in mg to mols of H + neutralized is given by, [H+] = 45 mg CaCO3 x 1 mol CaCO3 x 2 mol H + = 9.0 x 10-4 mol/L H+ L 100,000 mg CaCO3 1 mol CaCO3 Where the first term represents the reported

carbonate can be expected; h owever, rate increases of greater than 100% with 25% calcium carbonate in LLDPE film and 21% with 15% calcium carbonate in HMW -HDPE film have been observed. Physical property improvements have been noted in conjunction with the p roductivity increases mentioned.

Concentrated (e.g. above 72% by weight) dispersions of calcium carbonate ground to a particle size such that at least 87% by weight of the particles are less than 2 μm in size have a tendency to gel on standing. In the invention this tendency is minimized or eliminated by using, as dispersing agent, a copolymer of from 5 to 75% by weight AMPS and 95 to 25% by weight

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). None of these softer minerals are of concern for abrasion.
