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.

This conversion process is referred to as dolomitization. Dolomitization can take place almost immediately after limestone forms (penecontemporaneously), within a few days, weeks, or months of limestone formation (syngenetic dolomitization), or long after (years or even millions of years) (epigenetic dolomitization). Because virtually all dolomites were originally limestone it is appropriate ...

Limestone mining is done out in the open. Once studies show the existence of stone at the site, the extraction is made by separating the rock in quarry benches and dividing it into blocks. Before beginning the quarrying process, a resource analysis is made. This study investigates the existence and quantity of stone at the site and also the economic viability of the process. Normally the ...

Ground limestone or chalk (also called carbonate of lime or calcium carbonate CaCO 3) is the commonest material used at present. These are obtained by quarrying the limestone or chalk rock and grinding it to a fine powder. The finer the particle size the quicker the reduction of acidity. Some materials are obtained from industrial processes where lime is used as a purifying ...

escaped from the limestone during the calcination process. When this lime is exposed to water the water penetrates the cracks in the quicklime pebbles and fills these cavities. The hydration takes place quickly, releasing a lot of heat energy. This heat will boil off the water and generate steam, which makes the particles burst, exposing the inner surfaces to water for further slaking. This ...
