Abstract. Transport systems create a large share both in the initial investment costs and in the operating costs of open pit mines. The main competitive transport systems to be used in larger mines - the discontinuous material transport by trucks and the continuous material transport by belt conveyors -

Economic Filters for Evaluating Porphyry Copper Deposit

economic returns for copper deposits developed between 1989 and 2008. This correspondence demonstrates that the updated engineering cost equations are performing well and appear to be appropriate to evaluate the economic status of open-pit porphyry copper mines under current and potentially future economic conditions.
