摘要

The process of recovery, processing and purification of calcium carbonate generated by causticizing process (CaO + Na2CO3 + H2O -- CaCO3 + NaOH + water) of the pulp industry.This certificficado addition refers to an improvement of a process of recovery, processing and purification of the residue (CA CO3) generated in the process of oduu00e7u00e3o soda (NaOH) in calcium carbonate precicipitado.
