Abstract: Calcium carbonate (CaCO3) is the most widely used filler material in paper, paint, plastic, food, ceramic, cosmetic, medicine and other industries. In the present paper, precipitated calcium carbonate (PCC) has been produced from waste marble powder (WMP) by the Calcination-Dissolution-Precipitation (CDP) method.

In this process, calcium hydroxide is generated by treating lime (calcium oxide) with water. Then, calcium hydroxide reacts with soda ash (sodium carbonate) forming sodium hydroxide and Calcium Carbonate, yielding Precipitated Calcium Carbonate. A sodium hydroxide solution (50 wt%) is obtained as by-product.

Precipitated calcium carbonate, or PCC, is a synthetic calcium carbonate product. It is derived from, and possesses, the same chemical formula (CaCO3) as natural calcium carbonate (limestone), but is chemically purer than natural limestone. There is also much greater control of key characteristics, such as sizing and shape (see below on the PCC production process).

Carbonation is one of the two Primary Decolourisation technologies used in refined sugar manufacturing. It is based on the principle of Calcium Carbonate precipitate adsorbing the colouring matter thus leading to decolorization. Lime is pre-mixed with the Melt up to a certain pH and then CO2 is bubbled through it to form “in-situ” Calcium Carbonate. The Carbonate sludge …
