11.17 Lime Manufacturing 11.17.1 Process Description1-5 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.
Caustic-calcined magnesia (partially calcined magnesite) is used in the agricultural, chemical, construction, and manufacturing industries. 2 The most commonly used source for magnesia is magnesium carbonate, with the largest source being magnesia-rich brines and seawater.
