  • Key Issues Facing the Mining Industry in 2014

    In the case of low grade ore bodies, it is very important to remove as much of the desired ore from the mined material as possible in order for the mining operation to remain economically feasible. Miners must not only monitor the incoming material to maximize the extraction process, but the waste material must be monitored just as closely to
