Mantoverde

Mantoverde is an open-pit mine located in the Atacama region of Chile. It is currently comprised of four pits situated along the Mantoverde fault, each of which contains both sulfide and oxide ore. Mantoverde currently mines and processes only the oxide ore. Mining is performed using truck-and-shovel technology.

 

The high-grade oxide ore is crushed and leached on heaps and low-grade oxide ore is sent directly to leach dumps as run-of-mine ore. The resultant solution is collected and sent to the solvent extraction plant, which selectively removes the copper and leaves behind the remaining ions in the aqueous solution. The electrowinning process uses electrolysis to produce the high-purity LME Grade “A” copper cathodes.

 

Mantoverde owns a state-of-the-art desalination plant, which is located on the coast approximately 40 kilometers west of the mine. Our desalination plant supplies all water requirements for our current operations at Mantoverde with 120 liters per second, and will supply all water requirements for our expanded operation following the completion of the MV Development Project with 380 liters per second.

 

Annual production

 

The SX-EW plant has a production capacity of 60 thousand tonnes per annum of high-purity copper cathodes, with production in the range of approximately 40 to 50 thousand tonnes per annum.
