For bastnesite ore, which is the main rare earth resource in China, the ore or concentrates are typically roasted with H 2 SO 4, followed by leaching with water or dilute sulfuric acid. Rare earths are recovered from the leachate by solvent extraction with P204 (D2EHPA).
Geology. Niobium and tantalum are commonly found in the minerals pyrochlore and columbite. Cobalt is mined specifically from ores like cobaltite, but also as a byproduct of copper and nickel mining (Raymond, 1995). Lithium is found in three main types of deposits: brines, pegmatites, and sediments.

Rare earth elements (REEs) are a group of 15 chemical elements in the periodic table, specifically the lanthanides. Two other elements, scandium and yttrium, have a similar physiochemistry to the lanthanides, are commonly found in the same mineral assemblages, and are often referred to as REEs. REEs have not been mined in the United States for about 20 years, and prior to that time, the .
