RIO DE JANEIRO (Reuters) - Brazilian miner Vale SA said on Thursday it had begun using self-driving trucks for the first time at its Carajas complex, its largest iron ore mining operation, as it continues to expand its use of the driverless technology.
Vale expects to boost productivity and safety by using the trucks to haul iron ore, said Pedro Bemfica, the executive heading the autonomous technology program.
