Rare earth elements (REEs) are a class of active metals with an uneven spatial distribution. Owing to their unique spectrum and magnetic properties [1], as shown in Fig. S1a, they are widely used in various industries, such as the metallurgical, petrochemical, and glass ceramics industries; new materials; agriculture; and military cutting-edge weapons manufacturing.

Flotation—a method that separates materials based on differences in their surface wettability—is a process applied for both mineral processing and recycling of REEs, especially when the particles are fine and/or a high-purity …

The flotation process is considered one of the most important techniques to separate rare earth minerals from associate minerals and is commonly applied to the beneficiation of rare earth ores.

In this study, the Khalzan Buregtei deposit located in western Mongolia was studied with the aim of upgrading low-grade REE ore via magnetic separation techniques.

The flotation of rare earth oxides (REO) in monazite from mixtures containing monazite, hematite, and quartz with hydroxamic acid as a collector has been investigated using an IMN microflotation cell and a 1.2 L Denver flotation cell. Maximum flotation recovery of both monazite and hematite was attained at pH 7, whereas that of quartz, at pH 3.
