An Overview of Rare Earth Ores Beneficiation in Vietnam

Abstract

Rare earth metals are used in electricity, electronics, nuclear, optics, space, metallurgy,
superconducting and super magnetic materials, glass and ceramics, and agriculture. Some rare earth
elements are added to fertilizers for crops and some trials for animal feed. Rare earth elements, except
for radioactive promethium, are relatively abundant in the earth's crust. Vietnam has a tremendous rare
earth potential, distributed mainly in the Northwest, including Nam Xe, Dong Pao, Muong Hum, and
Yen Bai. There are many research projects on rare earth ores of different types globally, but the focus is
mainly on the essential minerals, including monazite, xenotime, and bastnaesite. This report summarizes
research data on rare earth ore intending to produce a general assessment of rare earth ore and its
beneficiation technology in Vietnam.
