Hindered-bed separators can concentrate particles based on size, density and shape. With feed stocks having a relatively tight size distribution, separations based on density and shape can be successfully achieved. Common applications include removing rock (SG 2.65) from coal (SG 1.35), upgrading iron ore, and the removal of silica from heavy-

Density-based separation of coarse iron ore was achieved using a gravity separator. • Coarse iron ore were efficiently upgraded by discharging waste gangue. ... Therefore, the high-density coarse iron ore particles were more likely to float on the bed surface and reduce the concentrate. Moreover, the movement distance of the coarse iron ore ...
Rough processing of iron ore employs dry methods which means that equipment is tuned to process large particles, but fine magnetic material less than a few tenths of a millimeter in size is not separated as efficiently. The relevance of this study is determined by the fact that dry beneficiation waste contains recoverable iron-bearing magnetite of commercial value. …

For the spiral concentrator the feed rate, slurry density and splitter position were varied. Test results indicated that FDS was highly selective in rejecting siliceous and aluminous gangue from iron ore compared to the spiral concentrator.
A dry density-based fluidized bed separator was used to beneficiate coarse particulate iron ore. The atomized iron powder and zircon sand, with specific size fractions of 150–75 and 250–150 μm, were mixed in certain proportion to form a binary dense media.

complexities of the ore, multi-stage dense media separators like the Condor can offer some advantages over the single-stage dense medium cyclones. The main advantage in using a multi-stage separator is the ability to produce multiple sink products and being able to fix the density cut points of each individual stage.
Wet High Intensity Magnetic Separators (WHIMS) from Multotec apply magnetism, matrix rotation and gravity to achieve para-magnetic materials separation. Applications include heavy minerals, ilmenite, manganese and iron ore (haematite) beneficiation; PGM upgrading as well as manganese recovery from slimes dams.
ABSTRACT A Floatex density separator was used to reduce the silica and alumina contents of a low-grade iron ore plant reject sample from the Pilbara region in Western Australia to produce a high-quality iron ore concentrate suitable for use in sinter and pellet blends. From a −2.0 mm head sample containing 49.42 wt% Fe, 12.77 wt% SiO2 and 4.90 wt% Al2O3, a product of …

Keywords: Floatex density separator, Iron ore fines, Alumina removal, Misplacement Introduction Significant amounts of fines are generated during mechanised mining and processing of iron ores. The generation of fines is more severe in Indian iron ores due to the soft and friable nature of hematitic and lateritic ores.1,2 These fines are best ...
