Toquepala operates an open pit mine and a conventional 60kt/d ore copper moly concentrator. An expansion to 120kt/d ore is expected for Q2 2018. The concentrate production is treated in the Ilo smelter and anodes are treated in the Ilo refinery. As part of our methodology the mine mill analysis is done in an integrated way. Toquepala also produces copper cathode by leaching low grade sulphide ore. The SxEw plant capacity is 56kt/a cathode.
