METHOD OF PRODUCTION OF CAUSTICIZED CALCIUM CARBONATE USING SCALLOP SHELL BAKED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a technique for improving the causticizing process in pulp production.

SOLUTION: In the causticizing process of pulp production, improvement of lime sludge dewaterability, decrease of dreg generation and, moreover, high whitening of calcium carbonate can be achieved by adding the baked products of scallop shells and a green liquor and performing causticizing reaction.
