Lime (material) Wikipedia

The process by which limestone (calcium carbonate) is converted to quicklime by heating, then to slaked lime by hydration, and naturally reverts to calcium carbonate by carbonation is called the lime cycle. The conditions and compounds present during each step of the lime cycle have a strong influence of the end product, thus the complex and varied physical nature of lime products.

Limestone

Limestone readily reacts with hydrochloric acid and produces carbon dioxide (CO2) as a gas. By contrast, dolostone is less reactive and normally must be in powdered form to react visibly. Pure dolomite contains percent calcium carbonate and percent magnesium carbonate. Dolostone is commonly referred to by its mineral name, dolomite.

What is Lime? | Mississippi Lime

Calcium oxide (CaO) or quicklime can be classified as either high calcium or dolomitic. High calcium quicklime has typically >97% CaO with magnesium oxide (MgO) levels less than 3%. At Mississippi Lime, our high calcium oxide (CaO) content is a result of our % pure calcium carbonate (limestone).

Lime Manufacturing US EPA

Lime Manufacturing Process Description 15 Lime is the hightemperature 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.
