Monazite is an important ore for thorium, [8] lanthanum, and cerium. [9] It is often found in placer deposits. India, Madagascar, and South Africa have large deposits of monazite sands. The deposits in India are particularly rich in monazite.. Monazite is radioactive due to the presence of thorium and, less commonly, uranium. The radiogenic decay of uranium and thorium to lead …

Monazite (REPO 4), a RE phosphate, is one of the primary sources of light REE (Kamitani, 1991). The most significant sources of this mineral are heavy mineral sands (Gupta and Krishnamurthy, 1992). Monazite is usually beneficiated from heavy mineral sands using gravity, magnetic and electrostatic separation (Bulatovic, 2010).
