Two reasons. First, there are several points in the PCC process where the calcium carbonate can be purified, removing much of the rock from the deposit that is not calcium carbonate—there are always some impurities in any limestone deposit. These include feldspar and other silicaceous minerals, as well as heavy metals.

OmyaWeb Precipitated Calcium Carbonate

Precipitated calcium carbonate (PCC) is produced by precipitating a calcium salt out of a solution under defined conditions. Normally, a filtered solution of calcium hydroxide Ca(OH)2 (from burnt lime) is used as the calcium source. This must not contain any colored impurities. Calcium carbonate is precipitated by the admixture of gaseous carbon dioxide or sodium carbonate Na2CO3.
