Hydrated lime ( or slaked lime) is usually a dry powder resulting from the controlled slaking of quicklime with water.

The exothermic or released heat of reaction is captured and used to evaporate the excess slaking water. For “slurry lime” excess water is not evaporated and the hydrate remains as a water suspension.


  • Metallurgy : Steel Manufacture, Steel Products Manufacture, Magnesium Manufacture, Alumina Manufacture, Ore Flotation and Non-Ferrous Metal Smelting.
  • Pulp And Paper : Sulfate Process, Sulfite Process, Bleaching, Precipitated Calcium Carbonate, Strawboard Manufacture, and in the treatment of pulp and paper mill liquid wastes, as a coagulant in color removal.
  • Chemicals : Alkalis, Calcium Carbide and Cyanimide, Petrochemicals, Bleaches, Dye and Dyestuff Intermediates and Coke- By-Products. In addition, it is used in the purification of citric acid, glucose and dextrin; metallic calcium; soda-lime, an adsorbent; and for countless other minor or isolated purposes, such as for CO, absorption.

Environmental Uses
