The basic processes in the production of limestone are (i) quarrying of raw limestone, (ii) preparing mined limestone for its use by crushing and sizing, (iii) calcining of raw limestone, (iv) processing the calcined limestone further by hydrating to produce hydrated lime if required for use, and (v) miscellaneous transfer, storage, and

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
