For the separation of nonferrous and rare metal ores containing a variety of useful minerals, the combined process of gravity separation-flotation separation-magnetic separation-electric separation is often used, in which magnetic separation is mainly used to remove magnetic minerals.
Gravity separation and magnetic separation are two common methods used in the mining industry to separate minerals and materials based on their specific gravity and magnetic properties, respectively. While they have similar principles, these techniques differ in terms of their applications, efficiency, and limitations.

Dry-type gravity separation technologies. Coal cleaning is mostly carried out by wet processes due to their high separation efficiency. However, wet processes consume large amount of water that are difficult for dry areas with limited water supply as well as the cold areas that are the temperature below the freezing point of water.
is widely acknowledged. Of interest is the magnetic separation, gravity concentration and sensor-based separation methods. The process of separating elements of value from gangue in ores depends on its chemical nature and mineralogical attributes hence the need for a profound characterization prior to physical separation.
Solid waste sorting is an important pre-treatment in recycling to improve the efficiency of material recovery and reduce costs. Motivated by the PEACOC project on metal recovery from solid wastes, an innovative magnetic density separation (MDS) process has been developed for solid waste sorting. It has intrinsic advantages over conventional gravity …
