CHAPTER 8 BENEFICIATION OF IRON ORES

CHAPTER 8 BENEFICIATION OF IRON ORES

Der Waals, and capillary. A magnetic separator is generally classified as low intensity if its maximum field intensity is less than about 2000 gauss (H= 1.6 x 105 A/m, B=0.20 T).' Low intensity magnetic separators (LIMS) are used to treat ferromagnetic and highly paramagnetic minerals such as iron and magnetite. High intensity magnetic separators

ADVANCES IN MAGNETIC SEPARATION OF ORES

ADVANCES IN MAGNETIC SEPARATION OF ORES

It is highly important to the iron ore industry that more efficient magnetic separators be developed. A speaker at the American Mining Congress in Sep- tember 1957 stated that the steel industry is shifting emphasis from cost of ore to cost of steel in the ladle. Further, it was claimed that steel costs can be reduced 264 per ton for each percentage point re- duction in silica content of concentrates such as …

Novel method for iron recovery from hazardous iron ore

Novel method for iron recovery from hazardous iron ore

Feb 10, 2018 Results of magnetic separation showed that the MFS concentrate grade was 74.02% Fe, with the recovery rate at 79.51% when the reduced samples were ground to 87.4% below 38 μm. This iron recovery increased by 4.19% compared with that of CMS, whereas the iron concentrate grade slightly changed.

Apr 22, 2019 The magnetic characteristics of the particle affect the force applied on it by a factor ranging from zero to approximately 0.5. The magnetic force applied on a particle is a direct function of the cube of its radius. Hence, the great importance of the size of particles In wet magnetic separation. The force is a direct function of both H and dH/dx.

Maximizing the recovery of fine iron ore using magnetic

Maximizing the recovery of fine iron ore using magnetic

Nov 15, 2016 The recovery of fine iron ore by magnetic separation will decrease with decreasing particle size because the magnetic susceptibility of magnetic particles decreases with a decrease in particle mass. There is an example of an Australian iron-ore operation that introduced beneficiation of fine haematite, -100 m, by using WHIMS2.

Wet Magnetic Drum Separator 911Metallurgist

Low-intensity separators are used to treat ferromagnetic materials and some highly paramagnetic minerals. Minerals with ferromagnetic properties have high susceptibility at low applied field strengths and can therefore be concentrated in low intensity ( ~0.3T) magnetic separators. For low-intensity drum separators used in the iron ore industry, the standard field, for a separator with ferrite ...
