Optimization of Acid Leaching of Rare-Earth Elements from

Optimization of the acid leaching process for Mongolian apatite-based ore containing rare-earth elements (REEs) was studied. The ore contained approximately 10% of REEs as total rare earth oxides, and the major impurities were Ca (33% as CaO) and Fe (23% as Fe2O3). Fe bearing minerals could be removed by passing the sample through a wet high-intensity magnetic separator before leaching.

Economic Analysis of Rare Earth Elements Extraction from

Rare earth elements (REEs) are a unique set elements that consist of fifteen lanthanide elements and yttrium, and are so called “rare” because most of them were originally isolated in the 18th and 19th centuries as oxides from rare minerals. Due to their reactivity, REEs are difficult to extract and refine to pure metals.

Rare earths: A review of the landscape

Jun 26, 2018· REEs are often subdivided into two groups, light rare-earth elements (LREEs) and heavy rare-earth elements (HREEs), based on increasing atomic numbers. Elements lanthanum (atomic number 57) through gadolinium (atomic number 64) are considered LREEs and have unpaired electrons ranging from 0 to 7, respectively.
