Rare earth metals mineral separation process for Brazil Rare earth metals, rare earth metals), also known as rare earths, is the generic terms of the 17 elements, commonly used R or RE said. Rare earth metal luster between silver and iron. Most of the rare earth metals present paramagnetism, gadolinium at 0 ℃ than iron has stronger ferromagnetic.

Gravity separation is an industrial method of separating two components from a suspension or any other homogeneous mixture where separating the components with gravity is sufficiently practical. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
