Separation Project

Rare earth elements are mainly lanthanide elements, including lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Te), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Y), and lutetium (Lu). Generally, scandium (Sc) and yttrium (Y) coexist in rare earth ore, also considered to be rare earth elements. Therefore, 17 rare earth elements and their various compounds range from chlorides with a purity of 46% to single rare earth oxides and rare earth metals with a purity of 99.9999%, which has widely application in the field of industry, society, medical treatment, and the environment. Since most of rare earth compounds can be obtained from high-purity rare earth oxides, the current purification and separation technology of rare earth elements are mainly concentrated on rare earth oxides (REO) and rare earth ore.


Our Services

In order to satisfy the production requirements, the rare earth minerals are separated from minerals and other useful minerals before smelting to increase the content of rare earth oxides and obtain rare earth concentrates that can meet the requirements of rare earth metallurgy and other applications. All rare-earth ores contain less than 10% rare earth oxide (REO), which must be increased about 60% before further processing. Therefore, the separates and refines of rare earth elements and related products are essential in production. Alfa Chemistry provides the professional separation and purification services of rare earth metal related products, including rare earth concentrates, rare earth elements, rare earth metals, and rare earth oxides et al, which also has a variety of environmentally friendly technologies, compared with traditional methods. Our service including but not limited to:

Why need rare earth purification?

Rare earth elements play vital roles in the development of today's technology, which have wide application in hybrid vehicles, advanced lasers for defense systems, vibrant flat screens, LED lights, medical equipment, catalysts, and optical fibers. The purity of rare earth elements greatly affect the performance of rare earth products, and the efficient separation methods will greatly improve the quality of finished products and finished products.

What are the applications of rare earth elements?

Owing to the special properties of rare earth elements in energy conversion, transmission and storage functions, magnetism and electricity, through the processing of rare earth raw materials, many excellent performance products has been developed such as rare earth permanent magnet materials, rare earth luminescent materials, rare earth laser materials, rare earth hydrogen storage materials, rare earth optical fiber materials, rare earth magneto-optical storage materials, rare earth superconducting materials, rare earth atomic energy materials et al.
