Paper thin markets? A look at PCC in paper

2019-4-3 · Precipitated calcium carbonate, or PCC, is derived from limestone, a fine-grained material that is generally greyish in color due to its organic content. If the limestone were crushed and fine ground, it would only have a brightness of ~80 ISO (on a scale of 0-100), which is too low for the material to be used as a filler and coating pigment.
