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.

Developments in the physiochemical separation of iron ore ...

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 chemical separation of iron ore ...

2015-1-1  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 magnetic separations between treatment steps.

2015-1-1  10.1. Physical processing for enhanced chemical and/or physical properties. Hematitic/goethitic iron ore as a bulk commodity is normally treated at its source (mine) through relatively simple physical ore dressing processes of comparatively large scale to turn it into salable products prior to transportation. The overall purpose of such treatment is twofold: In the first place, iron ore needs ...
