  • Iron Ore Archives - ASGCO | ASGCO

    At many operating mines, ore processing facilities (OPF) have been constructed to enable beneficiation of low-grade iron ores, including ores which have been contaminated with shale, to be mined and, after upgrading, sold as high-grade products. The operation of the OPFs has also increased the iron ore resources available at these mines.
