Calcium Carbonate - an overview ScienceDirect Topics

Depending on their origin and history of formation, and their impurities, the calcium carbonates have different properties. Three major technological processes are used in the production of calcium carbonate fillers: milling, precipitation, and coating. However, most calcium carbonate fillers are processed by milling using a dry or wet method.

Lesson 3 Forming a precipitate

2017-1-6  The precipitate is calcium carbonate, which is chalk and is also in eggshells, seashells, and coral. Looking at the chemical equation, the products are calcium carbonate, sodium chloride, water, and carbon dioxide. Carbon dioxide leaves the reaction as a gas and sodium chloride dissolves in the water, so the precipitate must be calcium carbonate.
