Abstract

A PROCESS FOR PRODUCING PARTICULATE CALCIUM CARBONATE BY WHICH THE AVERAGE LONGER DIAMETER OF THE CALCIUM CARBONATE CAN BE CONTROLLED IS DISCLOSED. THE SLAKING PROCESS IN WHICH QUICK LIME IS SLAKED WITH WATER TO PREPARE A SLAKED LIME SLURRY IS CARRIED OUT THROUGH TWO-STEP WET SLAKING PROCESS. IN THE FIRST STEP OF THE SLAKING PROCESS, IN WHICH WATER AND QUICK LIME ARE REACTED AND IN WHICH THE WATER/QUICK LIME RATIO CAN BE SELECTED, THE WATER/QUICK LIME WEIGHT RATIO IS SELECTED WITHIN THE RANGE OF 1.5 TO 10. INTO THE SLAKED LIME SLURRY PREPARED BY THE TWO-STEP SLAKING PROCESS, THE WATERQ/QUICK LIME WEIGHT RATION BEING CONTROLLED IN THE FIRST STEP THEEROF, CARBON DIOXIDE IS BLOWN TO CARBONATE THE SLAKED LIME. BY THIS, HIGHLY UNIFORM PARTICULATE CALCIUM CARBONATE HAVING AN AVERAGE LONGER DIAMETER OF THE PRIMARY PARTICLES OF 0.5 TO 10 ?M IS OBTAINED.
