Report summary

Mina Ministro Hales is Codelco's most recent project development and started in November 2013. It is located close to Codelco s Radomiro Tomic and Chuquicamata operations. The project comprised an open pit mine a 50 kt/d mill to produce 163 kt/a Cu and 287 t/a silver over a 14 year mine life. The ore contains significant amount of arsenic (around 1.6 1.9% As) that results in production of concentrate with As content just above 4%. To reduce the As levels a 550 kt/a fluid bed roaster was constructed to safely process copper concentrate and recover arsenic for further confinement. In addition to calcine and sulphuric acid the roaster produces flue dust (around 4% volume) containing 22% Cu.
