Solved Ore mineralogy: Main target and gangue
网页Gravity Separation: Gravity separation techniques can be used to separate the monazite mineral from the gangue minerals. Spirals and shaking tables are commonly used for this purpose. The high specific gravity of monazite (4.6-5.2 g/cm3) makes it possible to separate it from the gangue minerals, which typically have lower specific gravity.
