Dense media separators are commonly used for preconcentration of coal and diamonds but less commonly for other mineral systems such as lead and zinc. Due to lower head grades adding to the complexities of the ore, multi-stage dense media separators like the Condor can offer some advantages over the single-stage dense medium cyclones.

magnetic separation. Dry Magnetic Separation of Iron Ore There are many inherent advantages in processes that utilize dry magnetic separation to beneficiate iron ore. Wet concentration of magnetite ore, in comparison, re- quires 500 to 1000 gal of water per ton of concen- trate produced. This means extensive use of water
Magnetic Separation is one of the physical concentration processes that utilizes the differences in magnetic properties of various minerals present in the ore body. The magnetic fraction may be valuable or gangue depending upon its end use in a particular process and so also the non-magnetic fraction, e.g., separation of magnetite (magnetic)

magnetic separators. Dry magnetic separation is more controllable since the separation medium is air rather than water. Separating particles from one another is naturally easier without having to fight drag forces created by water. This creates a distinct advantage to using rare-earth dry
This is because conventional dry magnetic separators are e ective for processing ore feed with particles coarser than 75 m, which are spread in a monolayer over the separator 13. However, since low-grade ne-grained magnetite ores generally require milling the run-of-mine (ROM) ore to particles ner than 45 m, it renders the conventional ...
