Vale slashes iron ore sales estimate after dam burst

Brazilian miner Vale on Thursday estimated selling up to 75-million tonnes less iron-ore this year, after several mines were halted following its second deadly dam burst in less than four years.

The estimate, which is 20% below its prior forecast, is the latest blow to Vale from the collapse at Brumadinho, which killed some 300 people and forced the world's largest iron-ore exporter to fire its CEO earlier this month.
