  • Original Research Impact of Former Iron Ore Mining on Soil

    In comparison with modern methods, iron ore mines were not very invasive, which led to their excavated, post-mining remnants, commonly known as gob piles, having a very specific character. Gob piles are small heaps of unprocessed material extracted from deeper rock layers and piled up around the heads of old shafts [28]. In this way, the gob piles differ from typical heaps of post-mining waste

    mining, and the existing mines are having increasing difficulty in producing ore with a high grade of iron by simple screening. Currently, blast furnaces are mainly used for ironmaking. They would suffer from greatly reduced productivity and a high energy consumption rate, if low-grade ore were charged as-is. The same applies to direct reduction furnaces. Thus, there is a strong desire to

  • Iron Ore Processing for the Blast Furnace

    Mining Iron Ore Mining iron ore begins at ground level. Taconite is identified by diamond drilling core samples on a grid hundreds of feet into the earth. Taconite rock comprises about 28 percent iron; the rest is sand or silica. These samples are analyzed and categorized so that mining engineers can accurately develop a mine plan. To uncover taconite reserves, the mine area is first "stripped
