Thus, the primary crushing stage gives values of 0.0027 kg/t for the TSP emissions and 0.0012 kg/t for the PM10 emissions, while the sieving stage gives values of 0.0011 kg/t for the TSP emissions and 0.00037 kg/t for the PM10 emissions. In the load and haul processes, the waste needs to be handled at the dumping site.
