Plasma processing of iron ore fines iron ore fines having high silica content

Understanding the high-grade iron ore market An introduction to market dynamics and ... Iron ore lump and sinter fines are examples of ... such as Australia’s Pilbara and Brazil’s Carajas regions, where geological processes have led to iron content levels of between 55% and 65%. These ore types require little processing beyond

    High-grade iron ore fines are used for the preparation of pellets. Iron content in the ore has got to be very high and gangue low to confirm to the quality of pellets. The content generally is 66% Fe, SiO 2 + A1 2 O 3 - 3%, Sulfur and Phosphorus 0.05% each. The sizes of the fines should be minus 100 mesh 95% minus 325 mesh 60 - 75%

The only viable option currently is to dispose these slimes in tailing ponds for water recovery and future use. Due to increasing demand for steel and rapid consumption of high
