Rare Earth Flotation Fundamentals: A Review

During this time, a variety of collectors for the flotation of rare earths bastnasite have been investigated including: fatty acids, various hydroxamates, dicarboxylic acids, and phosphoric acids (Jordens et al. 2014).

A review of reagents applied to rare-earth mineral flotation

A review of reagents applied to rare-earth mineral flotation. The rare-earth elements (REE), which encompass the fifteen metallic elements of the lanthanoid series of the periodic table, yttrium and occasionally scandium, have gained enormous public, economic and scientific attention in recent years. These elements, which have been found in over ...

A review of reagents applied to rare-earth mineral flotation

Rare-earth mineral (REM) deposits can be broadly classified into four geological environments: carbonates, alkaline/peralkaline igneous rocks, placers and ion adsorption clays. Apart from ion adsorption clay deposits, which require no mineral processing steps, froth flotation is the most applied beneficiation technique. This paper reviews the flotation of REM, covering their

01.04.2016  1. Introduction. Rare earth (RE) minerals occur in peralkaline igneous rocks, carbonate-rich igneous rocks, iron-oxide–copper–gold mineralization, pegmatites, porphyry molybdenum ores, metamorphic rocks, stratiform phosphate residual, placers, laterites, and ion adsorption clays (Long et al., 2010).The beneficiation of the RE minerals from their ores

Search internet look at Chelgani et al., A review of rare earth minerals flotation: Monazite and xenotime, Int J Mining Sci and Tech (2015). This paper reviews rare earth minerals (monazite and xenotime) separation by flotation. A wide range of monazite and xenotime flotation test results are summarized including: reasons of variation in the point of zero charges on these

Foam flotation of rare earth elements by conventional and ...

01.11.2020  Foam (ion and precipitate) flotation is a promising green method of recovery of rare earth elements (REE) from leachates of the primary and secondary resources. However, the capabilities of foam flotation in solutions simulating real leachates are currently poorly understood, especially for green surfactants as collectors. In this work, we report the results of
