Dry beneficiation of iron ore
On account of the low process costs, DSO ores with iron content of 58 % are produced. For magnetite ores, beneficiation is typically more complex with finer ore grinding and downstream DMS (Dense Media Separation) and LIMS (Low-Intensity Magnetic Separation) separation processes. For DMS and LIMS, various technologies are used.

Dry beneficiation of high loss-on-ignition fly ash
Dry beneficiation of three high loss-on-ignition (LOI) fly ashes were conducted. The combination of two different types of dry separation techniques—ultrasonic sieving and triboelectrostatic separation—were used for this study. The results indicate that a simple separation of unburned carbon from fly ash is achievable at particle sizes of ...

Coal Beneficiation
Currently, the wet coal beneficiation process is the predominant method for coal upgrading. The wet beneficiation processes include heavy media separation, cyclone (water only), froth flotation, and spiral separation [23,24]. The use of these technologies depends on the particle size of the feed and the quality of the product required.

Beneficiation
11.5.3.1 Beneficiation. Mineral beneficiation begins with crushing and grinding of mined ore for near-complete separation of ore and gangue minerals as well as between ore minerals. Each processing step is designed to increase the grade (concentration) of the valuable components of the original ore.

Coal beneficiation: theory and practice
Dry coal beneficiation processes were widely applied in Europe and the United States during 1930–65. However, they were later abandoned largely because the separation was not accurate, the available technology severely restricted feed size and throughput, and moisture presented a major inhibiting factor on performance.

Iron Ore Beneficiation Technology By Electrostatic Separation
Almost of mined iron ore is used in steel production, making it essential for everything from staples to buildings. Beneficiation is the term for reducing the size of valuable iron ore particles and separating them from the gange (unusable minerals), which are then discarded. There are several different methods of wet and dry separation.
