During the carbonation phase of the sugar making process, hydrated lime is added and carbon dioxide gas is bubbled through. The lime and gas react together to form a chalk which attracts previously dissolved impurities. These impurities are then filtered out when the mixture is passed through very fine cloth filters, resulting in a purer sugar product.
This process is called as calcination. The solid product that remain after the removal of carbon dioxide in the calcium carbonate is called as the quicklime. CaCO 3 (Calcium carbonate) --> CaO (Calcium Oxide – …

Both quicklime and hydrated lime are dry bulk products derived from limestone (calcium carbonate, CaCO 3). The calcium oxide material known as Quicklime (sometimes called lime) is produced by heating limestone in a kiln to drive off carbon dioxide (calcination). Adding water to quicklime initially produces dry hydrated lime.
