The results showed that the REE are mainly mineralized as bastnäsite, monazite, and stetindite, along with uncommon minerals, such as brannerite, stillwellite, and florencite, for which there is limited processing data. In a preliminary effort to recover the REE, the tailings were subjected to gravity, magnetic, and froth flotation separation.

The presence of REEs in tailings of iron ore and apatite has been studied. REEs were found in fluorapatite, monazite, allanite (ce-bearing), xenotime (Y), light rare-earth element (LREE)-bearing epidote, and REE fluorocarbonates [88, 89]. Yang et al. investigated apatite vein-type REE from Mushgia Khudag, South Gobi, Mongolia.

Examples of placer deposits of REE include tin-rich river placers in Malaysia; paleo-placers in Witwatersrand, South Africa; Elliot Lake, Ontario, and beach sand deposits of Kerala, …

Long-term planning and processing design for Indonesian tin tailings should be designed, as other countries within Malayan tin belt such as Malaysia and Thailand have recovered monazite and xenotime as by-products from the retreatment of processing plant tailings earlier produced from tin placers (van Gosen et al., 2016). Euhedral-subhedral ...

The results of the study are that by using CT spiral, the monazite content has been enriched to 0.04% by weight from a feed sample containing 0.01%. The same has been further upgraded to 0.17% by weight using HG8 Spiral 1. HG8 Cleaner Spiral has further enriched the concentrate to 0.33% by weight. In the tailings, monazite contains …
