Iron ore and its beneficiation:

Magnetic separation and flotation are the most widely accepted technologies for the upgrading of iron ore particles, but these processes result in iron concentrate with high amounts of very fine and/or interlocked silica particles. Inferior sources of iron ore generally required beneficiation. Due to the high density of hematite relative to ...

Tungsten Ore Extraction Processing Mineral Processing

Currently, iron ore resources are embedded with fine particle size, and generally need to go through twostage grinding, and a few threestage grinding and sorting. Therefore, except for some coarsegrained tailings thrown out by preselection, most of the tailings discharged and stored in beneficiation have a particle size. It is relatively fine.
