As rare earth metal prices fall, the low-cost beneficiation of their minerals has become essential. Flotation-magnetic (FM) separation is a newly-developed technology for the economic recovery of rare earth elements from the Dalucao ore.
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.
Rare earths are critical components to many technologies that drive the modern world. Though rare earths are present in most parts of the world, they are produced mostly in China because of a confluence of several factors. This paper reviews various aspects of rare earths including extraction, geopolitics, and challenges.
Bastnasite is the primary valuable mineral in two of the world's largest rare earth (RE) mineral deposits and also found in Beylikova, Sivrihisar Rare Earth Oxide (REO) deposit.
