Chile mining now and projection
The investment for the industry for 2007 to 2011, was around US$22.000 million with a projected range from 5.560.000 to 6.700.000 FMT (fine metric tons) at 2015, that represent the increase the number of tailings dam and the volume of waste.
The largest open pit mine in the world
Soon isn’t be profitable, because the cost for operation are to high, for example, a truck must travel around 10,8 km to reach the bottom of the pit, so this truck spend 3.100 L oil per day, that spend a normal car 21 month. Ratio increased sterile and mineral. For that reason the objective now is get the mineral by underground mine with a calculated effective achieve mineral of 1.700 millions tons of copper and molybdenum, expanding the life of Chuquicamata until 2060.
