Calcium carbonate and adhesive residues

On March 22, Sally Power asked for opinions on applying talc or calcium
carbonate to sticky residues left from adhesives on paper.

In paper mills, when they have trouble with adhesive and resin globs in
the slurry, they use talc, even (I believe) for calcium carbonate-filled
paper.  They never use carbonate for this purpose.  Some carbonate is
abrasive, by the way--more abrasive than clay.
