2007-10-20 · Abstract:The fine crushing-wet preconcentration and grinding experiment is done on lean magnetite ore from Inner Mongolia area in China. The result shows that the low grade lean magnetite ore can be utilized as mineral resources in the condition of low developing cost by adopting fine crushing- wet preconcentration and grinding technology and special magnetic separator.
2008-11-1 · Computer simulation and mineral modeling was applied to the optimization of a grinding circuit in a plant processing 256 t/h magnetite. These tools were used to develop a grinding and classification configuration to decrease the grade of silica in the magnetite concentrate, which is produced by the plant. Empirical grinding and classification models were finely tuned using plant experimental ...
Although the majority of current steel production is supported by iron ore sourced from high-grade haematite deposits, the long-term growing demand for steel has led to higher raw material prices and opened the way for many new magnetite deposits to also be developed.
