Magnetic properties of an iron ore sample after microwave ...

2011-1-14  The effect of microwave radiation on the magnetic properties of iron ore was investigated. Increasing in radiation time up to 60 s results increasing total magnetism saturation and remnant magnetization. With further increasing in microwave radiation time to 120 s, the total magnetism saturation and remnant magnetization were decreased. Microwave radiation has a significant effect upon magnetic properties of iron ore.

Iron Ore Geoscience Australia

2018-12-31  Like hematite ores, magnetite ores require initial crushing and screening but also undergo a second stage of processing using the magnetic properties of the ore to produce a concentrate. Further processing of magnetite involves agglomeration 4 and thermal treatment of the concentrate to produce pellets. These can be used directly in blast furnaces or in direct reduction steel-making plants.

ADVANCES IN MAGNETIC SEPARATION OF ORES

2016-12-4  Dry Magnetic Separation of Iron Ore: There are many inherent advantages in processes that utilize dry magnetic separation to beneficiate iron ore. Wet concentration of magnetite ore, in comparison, re- quires 500 to 1000 gal of water per ton of concen- trate produced. This means extensive use of water resources, as well as disposal systems and some- times complicated water reclamation systems. Some of the new low grade iron ore

1998-2-1  Iron ore and host rocks have been sampled (90 oriented samples from 19 sites) from the Las Truchas mine, western Mexico. A broad range of magnetic parameters have been studied to characterize the samples: saturation magnetization, Curie temperature, density, susceptibility, remanence intensity, Koenigsberger ratio, and hysteresis parameters. Magnetic properties are controlled by variations in ...

2000-10-1  Rock magnetic properties are mainly controlled by variations in magnetite content, deuteric oxidation, and hydrothermal alteration. Magnetite grain sizes in iron ores range from 4 to >20 μm, which suggest the predominance of multi-domain (MD) states over single-domain (SD) and pseudo-single-domain (PSD) states.
