Jul 22, 2021 Brazilian iron ore export volumes in the first half of the year (H1 2021) rose 15 percent, year-over-year, according to data released by the Brazilian Mining Institute, IBRAM. IBRAM said Brazil’s iron ore export volumes in H1 this year reached 167.1 million mt, up from 145.4 million mt a year ago.
The Brazilian iron ore resources are shifting from high grade ores with good liberation at coarse sizes, to lower grade ores with good liberation only at finer sizes, requiring grinding down to a fine size to liberate and concentrate. Considering the very large throughputs required in the plants it is important to ensure the long-term economic and energy feasibility of this process.
Jul 29, 2021 Brazilian miner Vale SA flagged potential production setbacks on Thursday, amid temporary issues at multiple iron ore mines and an ongoing labor dispute at a major nickel and copper complex in Canada.
