Abstract
Los Pelambres Mine (hereinafter referred to as MLP) is located about 200km NE of Santiago in Chile.MLP is a porphyry copper deposit producing molybdenum as a byproduct. Annual production of copper concentrate in 2005 is 867,000t. MLP has two features in the mine site. One is that the strip ratio is lower than the other mines because the overburden was eroded by the glacier. The other is the electric generation using the downhill conveyer belt which transports ore mineral from the mine to the concentrator. Now MLP is going ahead with the construction of the new tailing dam (1,700 Mt) and increasing the mill throughput concentrate from 125,000 ton per day to 140,000 ton per day.
