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.
