The chemical industry uses lime in the production of a variety of chemicals including sodium alkalis, calcium carbide, cyanimide, citric acid, petrochemicals, propylene glycol glycerin, magnesia, calcium hypochlorite, and many others. These chemicals, in turn, are used in virtually every product in the United States.
A growing use for lime is the production of precipitated calcium carbonate, which is used in the production of paper, paint, ink, plastic, rubber, and some foods. The paper industry uses lime as a causticizing agent, for bleaching, and to produce PCC for their own use.
These and other key uses of lime, such as for sugar refining, refractories, and other food industries are discussed in this area.
