Iron ore tailings IOTs are common industrial solid waste products which are generated in enormous quantities during the production process of iron ore. By visual observation, this material shows some similarity with natural sand NS it was therefore desired to characterize the IOTs to further ascertain their use in concrete.
For more than three decades, barr has been helping a minnesota iron mining company with design and maintenance of its tailings basins and dams. the client wanted to replace a rock weir in its tailings basin that was difficult to raise, required constant maintenance, and exhibited a high risk of failure.
Effects of ration of coal to iron ore tailings on iron recovery. as shown in fig. 2, by the separation of magnetic separator, the grades of magnetic concentrate were all over 60 fe, meeting the required standard of iron making. when the ratio of coal to iron ore tailings was over 1100, the recovery rate of iron kept stable, and the maximum
