extraction of lime from limestone process

Lime Production from Limestone

Lime Production Process involves four steps: 1) Mining or Quarrying. Limestone material is extracted carefully to maintain its purity in underground mines and quarries all over the world. 2) Stone Preparation. In this step, the limestone is crushed and screened to further wash and remove impurities. 3) Lime Calcining (Conversion of limestone ...

Lime (material)

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.
