description of the production process for lime, with discussions of individual lime products, limestone inputs, and costs of production. Section 3 describes the characteristics, uses, and consumers of lime as well as substitution possibilities. Section 4 discusses the organization of the industry and provides facility- and company-level data.
Published March 2019. Lime, or calcium oxide (CaO), is derived through the decarbonation of limestone. The primary product of limestone decarbonation is called quicklime; it can be hydrated to form hydrated lime or calcium hydroxide (Ca[OH] 2).Quicklime is used primarily in metallurgy (steel) and flue gas desulfurization, while hydrated lime (also known as slaked lime) is used in construction ...
