Ore Sorting Strategies In Mineral Processing

Dense medium separators can also accommodate smaller particle sizes. Ore sorting can run into capacity and efficiency issues if particles are below 30mm. In contrast, dense medium separators can sort particles down to 0.75mm in size. If you’re working with finer particles, dense medium separation is the way to go. Higher tonnages can also be accommodated with dense medium separation

Gravity separation and Ore Beneficiation – IspatGuru

12/10/2018  Separation of the ore particle by gravity is dependent on two factors namely (i) settling rate of the particles, and (ii) difference in specific gravity when compared against the medium in which they are being separated, this gives differential settling rate and has been termed the ‘concentration criteria’.Settling rate of a particle is dictated by ‘Stoke law’ and is equal to kd2g(Ds ...

Ore Beneficiation - an overview ScienceDirect Topics

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. There are, however, other impurities in some deposits that ...

Mineral processing - Wikipedia

In dense media separation a media is created with a density in between the density of the ore and gangue particles. When subjected to this media particles either float or sink depending on their density relative to the media. In this way the separation takes place purely on density differences and does not, in principle, relay on any other factors such as particle weight or shape. In practice ...
