Production. Lime is made from indigenous limestone or chalk rock, one of the most abundant materials in the Earth's crust. Limestone and chalk are both sedimentary rocks and are chemically known as calcium carbonate. When crushed or ground, they are widely used as aggregates and building products. As a raw material, calcium carbonate can …
Rippers can be used for limestone mining as limestone is a 'rippable' sedimentary rock (refer to Sect. 3.1.1) Using rippers in small mines or for a group consisting of more than one mine is economical and productive. Instantaneous blasting or blasting with delay detonators in mines are executed in circuits.
