Separation process of iron ore,iron ore magnetic

2020-9-8  The flotation process is mainly used for the separation of fine-grained and particulate weakly magnetic iron ore, including two process flows of positive flotation and reverse flotation. Among them, the positive flotation process is suitable for quartz hematite ore without easy pumice gangue, and the reverse flotation process is suitable for ore with easy flotation gangue.

Developments in chemical separation of iron ore

2015-1-1  Gooden et al. (1974) reported that heating an Australian Pilbara iron ore at 1000–1300 °C in air and then leaching with 1% H 2 SO 4 at 50 °C, or 2% NaOH at 90 °C, for 1–5 h resulted in the phosphorus content being reduced from 0.11% to below 0.06% P. Similar results were obtained for pellets produced from various ores that had been fired at 1200–1300 °C (Gooden et al., 1973,

Dry separation of particulate iron ore using density

2013-3-1  Separations based on density-segregation are suitable for some tens or hundreds of μm-sized particulates but have generally not been applied to minerals. Here, we applied the dry density-segregation separation to particulate iron ore treatment. Particulate iron ore of +250–500 μm in size was fluidized at various air velocities. After the fluidization, bulk density and size fraction was measured as

Developments in the physiochemical separation of

2015-1-1  The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz. The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.

Developments in the physical separation of iron ore

2015-1-1  It is very difficult to produce a high-quality iron ore concentrate by magnetic separation alone for this type of iron ore. The ore is first ground using ball mills down to about 90% -75 μm. Drum LIMS are then used to take out the magnetite particles, while drum MIMS (0.4 T middle-intensity magnetic separators) are used to recover the martite grains.
