rare earth drum dry magnetic separation process

Rare-earth drum vs. rare-earth roll A RED is most often used to separate two or more paramagnetic minerals into separate finished products (or semi-finished products for further polishing) in the early stages of a dry separation process flowsheet. Additionally, a RED typically operates at higher unit capacity than a RER separator.

Separation of rare earths by solvent extraction using DEHPA

A current technological problem in the research for processing rare earth minerals is the separation of the mineral containing rare earth from the remaining minerals. For some mineral sources, these strategic elements can appear in very small particles, which creates a problem for the process of beneficiation.

Rare Earth Elements the 21st Century Minerals and China

The rare earth elements are all metals, and the group is also called the "rare earth metals." They have many similar properties that often cause them to be found together in geologic deposits. They are also referred to as "rare earth oxides" because many of them are typically sold as oxide compounds.
