CanadaÔÇÖs First Quantum Minerals is buying BHP Billiton's Ravensthorpe nickel mine on Western AustraliaÔÇÖs south coast for $340 million. The Vancouver, BC-based mining company plans to resume operations at the site, which was mothballed in January due to falling nickel prices, within 18 months. The mine was originally designed to process low-grade nickel laterite ore. The site cost BHP $2.2 billion to build but led to around $3.6 billion in writedowns after less than 12 months in operation. Almost 2,000 workers lost their jobs when the site was shut down.
