Rare Earth Ore Beneficiation plant
Rare earth mine in the earth’s crust mainly in the mineral form of existence, its mode of occurrence in three ways: as the basic elements of the mineral, rare earth ionic compounds occurrence in the mineral lattice, constitute a mineral essential ingredients. Of these minerals are usually referred to as rare earth minerals such as monazite, bastnaesite. To isomorphous replacement in the form of impurity elements as minerals, dispersed in the rock-forming minerals and rare minerals, these minerals can be described as containing rare earth elements in minerals such as apatite, fluorite. Showed a plasma state is adsorbed on the surface or particles of some minerals. Such minerals are mainly a variety of clay minerals, mica minerals. Such state of rare earth elements are very easy to extract. Rare earth ore processing equipment must be used, what does?
Rare earth ore beneficiation plant:
Rare earth minerals and associated gangue and other mineral physics, chemical properties, rare earth ore beneficiation methods usually are the following:
1, radiation processing method
The main advantage of the thorium content of the different rare earth minerals and gangue minerals in the ore, the use of the gamma-ray concentrator to separate rare earth minerals and gangue mineral. The radiation processing method used for the preselection of the rare earth ore. At present, this method is not widely applied in industry.
2, the gravity separation method
The use of different rare earth minerals and gangue mineral density separation. The re-election equipment cone concentrator, spiral concentrator, shaking (shaking table). The re-election so that the separation of rare earth minerals with low density of quartz, calcite and other gangue minerals in order to achieve the preselected enrichment of rare earth concentrates. Re-election of the GF for the seaside sands production; in the rare-earth veins in the ore beneficiation is sometimes used as a pre-enrichment means.
3, the magnetic separation method
Some rare earth minerals with weak magnetic. You can use them and the associated gangue and other minerals different than the magnetic coefficient, using different magnetic field intensity magnetic separator (magnetic the separator) to the rare earth minerals and other mineral separation. Beneficiation of beach sands, often using low intensity magnetic separation of ilmenite and monazite; can also be used to high intensity magnetic separation of monazite and zircon, quartz lamp mineral separation. In order to simplify the flotation process and save the flotation agent in ore beneficiation of rare-earth veins, sometimes using strong magnetic pre-enrichment of rare earth minerals. With the magnetic technology continues to evolve, the high intensity magnetic separation will become more and more widely used in the rare earth ore beneficiation process.
4, the flotation method
Use of rare earth minerals and associated mineral surface physical and chemical properties of the difference, using the flotation method with the associated gangue mineral separation concentrates, is the main mineral processing methods widely used in the current mine production of rare-earth veins. Mountain Pass rare earth mine is producing rare earth ore concentrate flotation. After re-election for re-sand beach sands production, are often severely sand flotation of rare earth concentrates.
5, electrostatic separation
The rare earth minerals are non-good conductor of electricity, can use its electrical properties and associated minerals are different, electrostatic separation and the conductivity of a good mineral separation. The electrostatic separation selected operations of the seaside placer re-election.
6, chemical processing method
REE deposit in the form of ion adsorption on kaolin or clay, you can take full advantage of the characteristics of rare earth ions soluble in the solution of sodium chloride or ammonium, the first leaching and then the precipitation of chemical processing to be recycled. Fluoro-carbonate rare earth minerals soluble in acid or a phase transition at high temperatures, can be the first flotation method pre-enrichment, followed by the chemical beneficiation methods of purification.
Rare earth ore processing equipment has?
From the above rare earth ore is mostly present in the ore where the rare earth ore processing equipment is a set of equipment, including vibrating feeder, jaw crusher, impact crusher, fine pure machine. Ball mill, flotation machines and other equipment. The use of each device vary. The entire rare-earth ore mineral processing equipment prices based on production in the different price difference, the greater the yield, the general price will improve. General hundreds of thousands to millions.
