During the last few decades, low-grade finely disseminated iron ore deposits have become the main sources of raw iron material in many countries. New technologies must be developed that achieve sharp separation at high throughput capacity, especially when treating very fine materials. These technologies must also maintain or improve current standards in more economic and environmentally attractive ways.
Iron Ore Beneficiation
Magnetic separation and flotation are the most widely accepted technologies for upgrading fine iron ore particles, but both processes result in iron concentrates with high amounts of very fine and/or interlocked silica particles. Gravity separation is a common process used in iron industry, but the separation efficiency becomes unacceptable with finely disseminated materials (
