The 800 Pound Gorilla in the room for rare earth

In fact monazite was first mined to produce thorium and rather than rare earths. In the 19 th century thorium was used to make gas mantles. Later with the development of technology that required rare earths to function monazite started to be mined for elements other than thorium. Meanwhile monazite itself is a by-product.
