The London Metal Exchange

Bloomberg photographers have documented a breathtakingly diverse world of work in 2012. From the frantic trading floor at the London Metals Exchange to precarious descents into Indian mines; from trudging across the frozen Yamal Peninsula to Gazprom's Bovanenkovo gas field and traveling through the night on West Virginian coal barges to mucking in with the animals at Lehmann Brothers Farms in Illinois, they haven't hesitated to get their hands, cameras and boots dirty.
