With no need for hard rock mining, crushing and milling, the cost of moving material from the stacks for re-processing will be much lower than those normally associated with mining a primary orebody. Cost of beneficiation to a mixed rare earth carbonate expected to be significantly lower than for a mined mineral rare earth project.
Rare earth elements can be found in a variety of minerals, but the most abundant rare earth elements are found primarily in bastnaesite and monazite. Bastnaesite typically contains light rare earths and a small amount of the heavies, while monazite also contains mostly the light, but the fraction of the heavy rare earths is two to three times ...
New way to explore for rare earth metals. Geologists and materials scientists at Friedrich-Alexander Universität Erlangen-Nürnberg (FAU) have discovered a new way of finding new and previously unknown deposits of rare earth metals, worldwide. They have published the findings of their study in the journal Geology.
By 2014, America's only rare-earth mine was producing 4,700 tons a year. But the mining industry operates without any particular loyalties. Australia opened the Mount Weld rare-earth mine in 2011;...

The new mega-corporation will be directly controlled by the State-owned Assets Supervision and Administration Commission (SASAC), an agency of the Communist government. The company will encompass about 70 percent of China's rare-earths industry. China, in turn, controls up to 85 percent of the world's entire supply of rare earth minerals.
Liquid-assisted grinding in a ball mill for 20 minutes gives crystalline homo- and hetero-rare-earth(iii) metal–organic frameworks by reaction between metal carbonates and benzene-1,3,5-tricarboxylic acid (H3BTC) in the presence of small amounts of DMF or water.
