Process for the control of pitch |
| abstract |
The present invention relates to a process for the control of pitch in an aqueous medium by adding surface-reacted natural calcium carbonate or an aqueous suspension comprising surface-reacted calcium carbonate and having a pH greater than 6.0 measured at 20 DEG C, to the medium, wherein the surface-reacted calcium carbonate is a reaction product of natural calcium carbonate with carbon dioxide and one or more acids, the use of the surface-reacted natural calcium carbonate for pitch control, as well as to a combination of a surface-reacted natural calcium carbonate and talc for pitch control, and the resulting composites. |
