Rare earth elements have been discovered since the end of the 18th century. At that time, people often referred to solid oxides which were insoluble in water as soil. Rare earth is rarely separated in the state of oxides, thus, these special minerals were called rare earth. As impurity elements of minerals, rare earth ore is dispersed in rock-forming minerals and rare metal minerals in the form of isomorphic replacement, which usually contains rare earth elements, such as apatite, fluorite, etc. It is often adsorbed on the surface of some minerals or between particles in the ionic state. As for the various clay minerals and mica minerals, rare earth elements in this state are easy to extract. There are different applicable separation methods for different rare earth minerals.
Rare earth ore mainly exists in the form of minerals in the earth's crust, and there are three main occurrence states: as the basic constituent element of minerals, rare earth is present in the mineral lattice in the form of ionic compounds, constituting an indispensable component of minerals, which are usually called rare earth minerals, such as monazite and bastnaesite. Alfa Chemistry mainly engaged in the research and development of production processes and equipment in the fields of single rare earth metals, rare earth alloys, and product deep processing. It can provide complete technology and equipment in the field of separation and purification, pyrometallurgy, hydrometallurgical separation, reduction-distillation, metal thermal reduction, alloy smelting. Alfa Chemistry also has a strong rare earth ore detection and analysis team, providing customers with customized services of high-quality rare earth purification solutions, including but not limited to:
❖ Rare earth element separation process development
❖ Clean metallurgical process development
❖ Comprehensive utilization of resources
❖ Process development for comprehensive utilization of secondary resources
Rare earth elements exist on the surface of the earth. Due to different regions, the composition of rare earth ore may be different. It is necessary to conduct pilot laboratory tests and pilot tests on specific minerals in order to form a final separation process suitable for the metal processing and metallurgical industry.
Alfa Chemistry provides the services of program customization, which including clean metallurgical process development, comprehensive utilization of resources, process development for comprehensive utilization of secondary resources, and rare earth element recovery process development.
