Vale’s iron ore production missed expectations in the fourth quarter as disruptions hit harder than analysts predicted. The Brazilian mining giant reported quarterly production of just under 90 million tonnes, when the results of its 50% share of production at shuttered mine Samaraco Mineracao and its third-party purchases are factored in. That marks a 4.9% slump from the prior quarter and a 0.2% dip from the final quarter of 2014.
