Developments in chemical separation of iron ore

2015-1-1  Chemical separation techniques for removing impurities from iron ores include caustic or acid leaching under a range of conditions. The leaching is usually preceded by a treatment to concentrate the impurity elements in the ore into a magnetic concentrate or to heat the ore to make the impurities more accessible to the leachant and so enhance their removal.

Chemical Separation an overview ScienceDirect

Chemical separation of impurity elements, such as silicon, aluminum, and sulfur, from iron ores often occurs in the processing to remove phosphorus from the ore. The treatments may include caustic or acid leaching of the ore, with or without a heating treatment, and

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.

Dry Magnetic Separation of Iron Ore of the Bakchar

2015-1-1  Magnetic separation is the only effective way of separating the valuable components of iron ore from the diamagnetic inclusions so far as the extractable iron compounds have a high magnetic susceptibility (as a rule, 20– 90·10-7 m3/kg8).

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.

Separation of iron from manganese ore roast‐leach

In this paper an attempt has been made to remove iron by aerial oxidation. Parameters such as pH, temperature and time were varied in order to arrive at an optimum condition. It was observed that at a temperature of 333 K, pH 5.5 and aeration time of 2.25 h the iron could be completely removed at an air‐flow rate of 1000 cm 3 min −1 without any loss of manganese.

Developments in the physical separation of iron ore

2015-1-1  Oxidized iron ores are much more difficult to upgrade by magnetic separators, because their magnetic susceptibilities are only about 1% or less of that of magnetite. In oxidized iron ore separation, it is therefore important to create magnetic fields with high intensities and high gradients to achieve higher iron recoveries. 9.3.2.1.
