Solar panels are seen during the inauguration of world's first-ever 'island' of solar panels in a tailings pond of the Los Bronces copper mine of Anglo American, on the outskirts of Santiago, Chile March 14, 2019. Miner Anglo American on Thursday, March 14, 2019, completed the installation of a floating island of solar panels in a tailings pond associated with its flagship Los Bronces copper mine outside the Chilean capital of Santiago, a bid to boost efficiency at the deposit.

The 256 panels, tethered to the bottom of the artificial lagoon to ensure proper orientation even in strong winds and changing water levels, have the capacity to produce 86 kilowatts, the company said.

Global miners are increasingly seeking innovations to boost efficiencies, lower costs and reduce use of water at mines. In Chile, the world's top copper producer, that has largely meant a turn to solar power and desalinated sea water. REUTERS/Rodrigo Garrido
