Vale's iron ore production will be impacted by at least 50 million tonnes this year and supply could be disrupted until 2024, according to new forecasts.
The miner estimates its 2019 sales volumes will be between 307 million and 332 million tonnes, down from an earlier estimate of 382 million tonnes.
The revised estimate "involves market factors that are beyond the control of Vale and, therefore, can be subject to new changes", according to a press release on Thursday.
