  • Dolostone Limestone

    Dolostone Limestone

    Limestone and dolostone are quarried from open pits and underground mines. Drilling and blasting releases the stone from the outcrop and provides first-order breakage. The rubble is then hauled to a crushing facility where the stone is further crushed, screen-sorted into size classes, and stored.

    Project Description

    Mining recovery is assumed to be high with values ranging from 95 - 100. Dilution is projected to be minimal since the nature of the deposit is inherently homogeneous and the mining process is well-established and practiced in quarries of the same or related industry such as cement. All oversize will be recovered and will undergo comminution.
