2019-9-2  Rare Earth Elements in Australian Heavy Mineral Sands Deposits. Rare earths-bearing minerals monazite and xenotime occur in many of Australia’s heavy mineral sand deposits and, up until the mid-1990s, monazite was produced from them and exported, mainly to Europe. A brief overview of these activities is given by Hoatson et.al (2011) 138.

2021-5-25  In some cases, rare metals occur in the form of independent rare-element minerals; in other cases, they are present as impurities in carrier minerals, which constitute the ore of non-rare metals, while more rarely, the rare elements are dispersed in nonmetalliferous rock-forming minerals. Many factors crucial for the formation of rare-metal ...
