Sugar production involves two distinct operations: (a) processing sugar cane or sugar beets into raw sugar and (b) processing the raw sugar into refined sugar. Cane and beet sugar extracts contain sucrose and undesirable amounts of polysaccharides, lignins, proteins, starches, gums, waxes, and other colloidal impurities that contribute colour and/or taste to the crystalline product and reduce ...

11.17 Lime Manufacturing 11.17.1 Process Description 1-5 Lime is the high-temperature product of the calcination of limestone. Although limestone deposits are found in every state, only a small portion is pure enough for industrial lime manufacturing. To be classified as limestone, the rock must contain at least 50 percent calcium carbonate.

A more recent development for hydrated lime use is in environmental applications. Here, hydrated lime, a mild alkali, is used for the removal of acid gases in coal-fired energy plants, cement mills, glassmakers and incinerators. 1. However, the largest single use of hydrated lime remains steel manufacturing, where it is used to remove impurities.

Hydraulic lime can be considered, in terms both of properties and manufacture, as part-way between non-hydraulic lime and OPC. The limestone used contains sufficient quantities of clay and/or silica. The resultant product will contain dicalcium silicate but unlike OPC not tricalcium silicate.
Precipitated Calcium Carbonate. PCC stands for Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate. It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3. The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three different calcium carbonate minerals.
