Chilean state-miner Codelco has restarted operations at the Radomiro Tomic, Ministro Hales and Chuquicamata copper mines in the country's Antofagasta region after severe weather caused a series of precautionary closures, Reuters reported June 8.

The mines in northern Chile are now operating normally.

Meanwhile, the company's Salvador division, including an underground mine and a port, are also operating normally, and Codelco expects Salvador's foundry and refinery to fully restart operations shortly.

The miner is evaluating the storm's impact on production.

Heavy rain and snow in the northern part of the country resulted in the suspension of several mining operations, including the BHP Billiton Group- and Rio Tinto-owned Escondida and Antofagasta Plc's Zaldivar copper joint venture.

Glencore Plc's operations at its two Chilean mines were partially closed, while Poland's KGHM Polska Miedz SA also reported disruptions.
