    Abstract: An improved belt for use in a belt separation apparatus and an improved method to separate a particle mixture based on tribo-electric charging of particles is disclosed. The improved belt is particularly suitable for tribo-electric separation of particles that tend to accumulate on the edges of the belt separation apparatus and/or tend to compound, or blend, with the belt material. The improved belt comprises impermeable longitudinal edges, apertures interior to the longitudinal edges of the belt, and periodic notches formed in the longitudinal edges of the belt at periodic locations in the edge of the belt.

    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%.
