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%.
A system for beneficiation of fine and very fine particles of iron ore, comprising:
A system for beneficiation of fine and very fine particles of iron ore, comprising:
The system of any of the preceding claims, wherein the first BSS receives and processes a stream of particles having a median particle size (d50) of 70 μm or less.
The system of any of the preceding claims, wherein the first BSS receives and processes a stream of particles having a median particle size (d50) of 50 μm or less.
The system of any of the preceding claims, wherein the first BSS receives and processes a stream of particles having a median particle size (d50) of 25 μm or less
The system of any of the preceding claims, wherein the first BSS receives and processes a stream of particles having a median particle size (d50) of 10 μm or less.
The system of any of the preceding claims, wherein the iron ore comprises one or more of hematite, goethite and magnetite, in varying proportions.
The system of any of the preceding claims in which the iron ore is associated with gangue minerals selected from the group including but not limited to:
The system of any of the preceding claims, wherein the iron ore comprises additional iron minerals including siderite and/or lepidocrocite.
