Engineering, supply and construction of the dome and auxiliary systems. This project contemplates the transport of copper concentrate from the filtration plant to a reinforced concrete dome, where it is stored (30.000 metric tons), using a tubular conveyor belt. The concentrate is distributed by a stacker; a reclaimer takes it to the main hopper, unloading into two underground conveyor belts, which take the concentrate to the Roasting Plant.
