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.

Once the ore is on the surface, the process of getting the mineral you want out of the rock can start. Once the mineral is separated from the rest of the rock, the mineral needs to be cleaned so that it can be used. This process can be represented by the following flowchart diagram: In this chapter we will look at each of the steps in more detail.

2013-12-24  Mechanized mining operation along with its multiple advantages brought drastic changes in the ROM iron quality by increasing the fines and dirt. Surface property- based separation processes such as froth flotation and agglomeration are very selective in rejecting well-liber-ated mineral matters. However, efficiency of these proc-esses gets reduced if the feed contains disproportionate amount of composite particles. Surface based separation processes are very intricate, needs close attention and careful operation where as the conventional gravity- based separation

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.
