A papermaking process wherein calcium carbonate is included in a pulp suspension. The dissolution of the calcium carbonate in the papermaking system is substantially retarded by the introduction of carbon dioxide to said pulp suspension. The invention also provides processes for the production of paper or board in papermaking systems wherein solid calcium carbonate is …
There are four popular minerals used in paper filling and coating: kaolin clay, calcium carbonate (available as ground or precipitated), titanium dioxide and talc. Both titanium dioxide and talc, however, are consumed in small quantities for special applications where extreme whiteness and opacity, or pitch control are required.
This material can be shipped out in tankers, dried, or fed to other bacterias to make yeast. The Kraft mill also uses other chemicals such as sodium hydroxide (caustic soda) and sulfuric acid. Kaolin (slurry form) is brought in to make glossy paper. Kaolin is often supplemented by calcium carbonate (lime) slurry and titanium dioxide.

Full Article. AKD Sizing Efficiency of Paper Filled with CaCO 3 from the Kraft Causticizing Process. Jian Wang, a,b, * Ling Liu, a Zhijie Wang, a and Yongjian Xu a Causticizing calcium carbonate (CCC), known as lime mud, is a by-product of the papermaking industry that comes from the green liquor causticizing process.
Precipitated calcium carbonate is the most cost-effective mineral for producing high quality paper and paperboard via substitution of more expensive wood pulp, additives or other minerals. The use of PCC as a filler has been growing at a phenomenal rate since Specialty Minerals' first satellite facility was installed in 1986.
water-repelling efficiency of the coated paper was highly dependent on the ratio of / PCC as well as the binder content in the coating SA formula. PCC particles modified with 12wt% SA were efficient in increasing the water contact angle (WCA) of the coated paper to 146° at a coating weight of 5 g/m. 2
