RIO DE JANEIRO, Oct 19 (Reuters) - Brazilian mining company Vale SA reported a rise in iron ore output in the third quarter, in part due to restarts at mines that had previously faced regulatory and coronavirus-related concerns.

In a securities filing on Monday, the company said it produced 88.7 million tonnes of iron ore in the quarter, up 31.2% from the previous quarter and up 2.3% from the same period a year before.
