Once limestone face is exposed drilling/cutting the limestone begins. The saw usually has diamond in it to make it sharper; The limestone blocks are then taken away to a factory, usually a concrete factory. In a concrete factory the limestone is put in a rotary kiln where hot air and limestone is pumped in and 'lime' is produced as well as CO2.

Two general phases of granite production exist: quarrying and processing. Each of these phases is described below. 2.2 Granite Quarrying Operations Extraction (more commonly referred to as quarrying) consists of removing blocks or pieces of stone from an identified and unearthed geologic deposit.

This study presents a novel method to estimate the aggregate pollution index (API) within the residential communities around a limestone mining and cement producing environment.
limestone quality is determined based on the desirable oxides of calcium, silica, aluminum, and iron i.e. CaO, SiO2, Al2O3, Fe2O3 [1]. Limestone also contains some undesirable oxides like MgO, SO3, K2O, Na2O, and P2O5, etc. The raw mix for the cement plan is dependent upon the quality of limestone mined at a specific period.
