Tombarthite introduction

Tombarthite (rare earth) mainly exists in the crust in the form of minerals. There are three kinds of state. The first is the basic composition element in the mineral lattice which is essential composition to minerals. It’s usually called Rare earth minerals, such as monazite, bastnaesite, etc. The second kind is those minerals which contain rare-earth element, such as apatite, fluorite, etc. The last is the various clay minerals and mica minerals.

There are mainly four kinds of minerals used in the industrial extraction of rare earth: Bastnaesite, single quarry, xenotime and Weathered Elution-type ore. The first three accounted for more than 95% of rare earth mineral productions in the West. In monazite and bastnasite ore, it is of high content of light rare earth. Differently it is heavy rare earth and yttrium which are high in xenotime.

Global rare earth(Tombarthite) production

Until 1948, most of the world‚ Äôs rare earths were sourced from placer sand deposits in India and Brazil . Through the 1950s, South Africa took the status as the world‚Äôs rare earth source, after large veins of rare earth bearing monazite were discovered there. Through the 1960s until the 1980s, the Mountain Pass rare earth mine in California was the leading producer.Today, the Indian and South African deposits still produce some rare earth concentrates, but they are dwarfed by the scale of Chinese production. China now produces over 97% of the world‚ Äôs rare earth supply, mostly in Inner Mongolia , even though it has only 37% of proven reserves. All of the world‚Äôs heavy rare earths (such as dysprosium) come from Chinese rare earth sources such as the polymetallic Bayan Obo deposit.
