THIS invention relates to an integrated process for recovering the valuable iron fraction from low grade iron ore, including the steps of: comminution 14 and classification 36/39 to obtain a classified fraction suitable for coarse flotation and classified fraction suitable for fine beneficiation; subjecting the fraction suitable for coarse flotation to coarse flotation 40 to obtain an
The SGM MIMS separator features an innovative proprietary magnetic circuit that results in a unique substantially homogeneous (both axially and radially) high magnetic field and high gradient along its whole magnetic arc which makes it extremely performing on low magnetic susceptibility iron ore both in terms of recovery and purity. Placed
Feb 16, 2012 The magnetic hydroseparator is described. Thanks to the replacement of magnetic separation drums by hydraulic separation, this new system for extracting hematite (and the magnetite that it contains) permits extraction levels greater than 5%. As a result, the metal balance in blast-furnace smelting may be improved, with corresponding gain in blast-furnace efficiency, reduction in coke

Dec 01, 2002 The magnetic separation was performed with a Frantz Isodynamic Separator and the electric current was set at 0.3 A (magnetic field intensity: 0.24 T). When Fig. 5 is compared with Fig. 1 , and Fig. 6 compared with Fig. 2 , it is clear that at a magnetic field intensity of 0.12 T, recovery of ilmenite into the magnetic products coincided well
Jan 14, 2011 Abstract. The effect of microwave radiation on the magnetic properties of an iron ore was investigated. Four samples from Choghart Iron ore were used in this research. Three samples were treated for 30, 60 and 120 s respectively, in a multi mode microwave oven with a frequency of 2.45 GHz and a maximum power of 1100 W
Concentration Of Ore By Gravity Separation. Gravity concentration is the separation of minerals based on differences in specific gravity a gravity concentration process is designed to recover very high grades of valuable ore material into very small masses the resurgence of gravity concentration in mining has come about due to its simplicity and low environmental impact
Mar 11, 2018 The fluidized bed reactor uses iron ore fines which limits the need for pre-treatments such as sintering or pelletizing. The ideal feed material for the reactor is the hematite iron ore fines with its size in the range of 0.1 mm to 1.0 mm. The inside diameter of the reactor is around 12 meters and operates at around 600 deg C
Real life examples of magnetic separation. gravity separation examples, gravity separator, magnetic seperator,magnetic separation chemistry Iron Sand Processing Plant is applicable for wet magnetic separation of materials such as magnetite, pyrrhotite, roasted ore and ilmenite whose size is less than 3 mm and also used for iron
Fully automatic elutriation magnetic separator utilizes its unique “magnetic suspension” technology and realizes a large size of equipment. The diameter of the separating cylinder ranges from 400 to 2,400mm. The elutriation magnetic separator which handles over 150 tons of dry ore
Mar 13, 2013 A further prior document, U.S. Pat. No. 3,021,951, refers to an inner drum magnetic separator with several magnet devices alternating north and south, which in the bottom of the drum collects the magnetic minerals of high magnetic susceptibility, such as metallic iron in the recycling of industrial and household waste, made of ferrite magnets (iron-boron), with a maximum intensity of
Magnetic elutriation improves the quality of low-grade domestic iron ore by using an alternating-current, pulsed-magnetic field to clean iron ore into a highly refined product. This innovative process differs from conventional drum type magnetic separation systems by using permanent magnets that cause magnetic entrapment

United States Patent 3615339. Abstract: A process for producing iron powder in which a hematite ore concentrate is ground and passed through a high-intensity wet magnetic separator to remove silica and other acid insoluble impurities, after which the purified hematite is reduced in the presence of hydrogen to form iron powder. Inventors:
The refractory iron ore treated by the present method can be produced to homogeneous magnetite or maghemite accurately, and through magnetic separation, on-line grade analyzer detection and ore-like splitter, the concentrate powder which reach the set grade can be obtained, and the unqualified ore powder enters the next stage of oxidation
Particulate mixtures of non-magnetic or paramagnetic materials are separated by selectively coating the surfaces of a component or components of the mixture with a magnetic fluid. Thereafter, the particulate mixture is subjected to a magnetic separation yielding a magnetic fluid-coated fraction and a non-magnetic fraction. The process is especially useful in mineral beneficiation wherein a
