There is no obvious limit on the concentration of coarse magnetic separation, but the material concentration should not be too low to effectively control the negative fluid force during the mineral processing operation. When magnetically selecting fine particles, the concentration is required to be high to ensure the recovery of magnetic minerals.

Beneficiation (e.g., froth flotation, magnetic separation, gravity separation) of REE minerals have become increasingly complicated, especially where ore grade is significantly low [<1% total REO (TREO)]. Typically, low-grade ores are dominated by fine- to ultrafine gangue minerals, including silicates, carbonates, and phosphates.

In simple words, the concentration of ore is the method of separating ore from the gangue, as the gangue or matrix particles are the valueless substances that are of no use. The ore can be concentrated or separated by both physical and chemical means. The ore obtained after the completion of the ore concentration is called concentrate. What is Ore?
