Rare Earth Minerals Processing

The common rare earth beneficiation technology is as below. Gravity separation: Gravity separation of rare earth minerals is carried out by using the density difference between rare earth minerals and gangue minerals. For example, coastal placer mineral containing rare earth often adopt gravity separation and rare earth vein ore always use gravity separation for pre-concentration. Flotation ...

The main method for beneficiation of copper-nickel sulfide ore is flotation, while magnetic separation and gravity separation are usually auxiliary beneficiation methods. When flotation of copper sulfide nickel ores, collectors and foaming agents for flotation of copper sulfide minerals are often used. A basic principle for determining the flotation process is that it is better to allow copper ...
