Codelco Begins Gradual Restart at Chile Mine Hit by Collapse

Codelco restarted underground and processing activities at its biggest copper mine, El Teniente, a little more than a week after suffering Chile’s deadliest mining accident in decades.

The state-owned company restarted operations over the weekend at eight underground areas deemed safe by mining and labor authorities, as well as at its smelter, Codelco said. Four other sections of the mine — near where the July 31 collapse occurred — will remain off limits as an investigation continues.
