    1st ball mill grinding. Crushed iron ore is moved by belt conveyor to ball mill for grinding, after which, 36% of iron ore is grinded into 200mesh in size. Double spiral classifier and cylinder screen are used to separate large particles from grinded product. Wet ball mill is usually used in metal ore processing plant.

  • 11.23 Taconite Ore Processing

    Processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore concentrate. A simplified flow diagram of these processing steps is shown in Figure 11.23-1.
