What is the rarest ore in Earth?

The main rare earth ores are monazite, bastnaesite and xenotime. Monazite is largely a light rare earth (La, Ce, Pr, Nd) phosphate (93–94%) and is often found as a component of mineral sands, which are usually mined primarily for ilmenite, rutile and zircon. Bastnaesite is even more dominantly a light rare earth (ca.
