Brazil's Vale says starts tests at its biggest ever iron-ore mine

Brazil's Vale, the world's largest iron-ore producer, said Wednesday that it began testing equipment at its $14.4-billion S11D mine at its massive Carajas complex, in the Brazilian Amazon. The mine is the company's largest ever. Tests began with the 9.5-km conveyor belt that takes iron-ore from the mine's opencut pit to its processing facility, said Jamil Sebe, head of iron-ore project implementation for the company's Amazon iron assets.
