About Us Azulinvest S.A, founded in March 1995, specializes in the production and trading of rare and strategic industrial metals. Our production unit partner New Technologies based in Moscow, aims to allow a controlled supply, from the production mines to our area of manufactured products thus benefiting from quality inspections by recognized international laboratories and therefore importing ...
Rare earth extraction is one of the most environmentally destructive and toxic producing of all mining practices. Excessive rare earth mining has resulted in landslides, clogged rivers, environmental pollution emergencies and even major accidents and disasters, causing great damage to people's safety and health and the ecological environment.
What Are Rare Earths? Rare earths are a series of chemical elements found in the Earth’s crust that are vital to many modern technologies, including consumer electronics, computers and networks, communications, clean energy, advanced transportation, health care, environmental mitigation, national defense, and many others.
Rare earth metals are actually not as rare as their name might imply. They are critical to high-performance optics and lasers, and essential to the most powerful magnets and superconductors in the world. Rare earths are simply more expensive to mine than most metals when not mined with environmentally harmful chemicals. These metals are also ...

The detailed market intelligence report on the Global Rare Earth Metals Market applies the most effective of each primary and secondary analysis to weighs upon the competitive landscape and also the outstanding market players expected to dominate ...
Rare earth elements-bearing minerals, once separated, contain as many as 14 individual rare earth elements (lanthanides and yttrium) that must be further separated and refined. The complexity of extracting and refining rare earth elements is illustrated by a metallurgical flow sheet for the Mountain Pass mine in California (fig. 2).
Rare earth Sulphates. RE sulphates are generally prepared by adding sulphuric acid to their corresponding oxides, hydroxides, carbonates, and the solid state of the salt can be prepared by condensation of the solution. All RE sulphates are soluble in water, but their solubilities are lower and down with the temperature up. Rare earth Carbonate
Neodymium Magnet Information Magnet Terminology. The terminology of magnetics is not widely understood. You can find definitions of most terms on our Glossary of Magnet Terminology Page. Rare Earth. Neodymium magnets are a member of the Rare Earth magnet family and are the most powerful permanent magnets in the world.
Rare earth element–bearing minerals have highly variable metallurgical responses, to both chemical and physical treatment, and even in the same mineral group there can be significant differences in crystal chemistry, which result in different processing (Hellman and Duncan, 2014).

Jun 22, 2018· The rare earths share many common properties. This makes them difficult to separate or even distinguish from each other. There are very small differences in solubility and complex formation between the rare earths. The rare earth metals naturally occur together in minerals (e.g., monazite is a mixed rare earth phosphate).
