Abstract
Systems and methods for the beneficiation of fine and very fine particles of iron ore are disclosed. The system includes a first triboelectric electrostatic belt-type separator (BSS) which receives and processes a stream of particles with a median particle size (d50) less than 75 microns to generate an iron rich concentrate. The system and method is water- free and carried out in a totally dry metallurgical route. The system also includes at least one air classification device that receives and processes a feed stream of particles to provide the stream of particles with a median particle size (d50) that is less than 75 microns. The system may also include a dryer and de-agglomeration system that receives a feed stream of particles and processes the feed stream of particles to provide the particle stream with a moisture of less than 2%.
