Study Of Malaysian Rare Earth Elements: Mineral Characterization Of Monazite And Xenotime Concentrate From Amang [PDF]
, 2022 Amang, widely recognized for mineral tailings in Malaysia, is a cassiterite-tailing or tin oxide (SnO₂) secondary product inevitably formed from mineral separation processes such as gravitational, magnetic, and high-tensional separators.
