Portable XRF instruments can provide real-time, on-site assays of REEs and other elements in any type of geological samples, including elements associated with REE-bearing minerals. By using the concentrations from these elements, it is possible to infer concentrations of heavy REEs HREEs that are commonly associated with host minerals.
Researchers continue to develop new technologies to recover rare earth elements REEs. XRF analyzers are also used to positively identify the chemical composition of numerous metal alloys. Several new REE recycling technologies have been developed, including ones that involve using a nanofiltration system to extract and separate rare earth metals from phosphoric acid and waste, and using a combination of hollow fiber membranes, organic solvents, and neutral extractants to selectively recover rare earth elements.

China's reserves of rare earths amounted to an estimated 4.
Global snapshot of rare earth reserves According to estimates, the total worldwide reserves of rare earths are approximately million metric tons. Most of these reserves are located within China, and are estimated at some 44 million metric tons.
The United States also has significant reserves, estimated to amount to 1. After China, the major rare earth countries based on reserve volume are Vietnam, Brazil, and Russia. The largest rare earth producers With over , metric tons produced from mines in , China was also the world's largest producer of rare earths. China produces most of its rare earths in the southeastern part of the country, such as in the provinces Jiangxi and Fujian, however production also occurs in other parts of the country such as Inner Mongolia and Sichuan.
The United States, which is the second largest producer of rare earths from mines, extracted some 38, metric tons of these mineral commodities in the same year. Breakdown of rare earth elements: end uses and different types Rare earth elements, also called rare earth metals, are a group of 17 chemical elements.
The largest subgroup within it are the 15 lanthanides. The two other elements are scandium and yttrium. Based on quantity, the lanthanides cerium, lanthanum and neodymium are the most produced rare earths elements.
Yttrium, one of the rare earths that was explored first, got its name from the town where it was discovered — Ytterby, Sweden. Nowadays, rare earth elements are crucial for a number of key technologies such as medical technology and energy technology. It has a resource of about , tons at an average grade of Why Indian govt does not raise capacity of rare earth production despite potential since so many years?
