Crushing section: Utilize coarse jaw crusher, fine jaw crusher and vibrating screen to …

Spodumene concentration is a complex process involving dense media separation (DMS), flotation, and magnetic separation. DMS typically processes coarse material (>850 μm) and can produce a coarse final spodumene concentrate while often also acting as an upstream upgrading stage for the flotation feed.

The ultra-strong magnetic head roll of the RE Roll enables the separation of ferromagnetic, paramagnetic and weakly magnetic minerals such as muscovite mica. The RE Roll is often preferred to other high-intensity magnetic separators (such as the Induced Magnetic Roll Separator) as the magnetic field is produced with permanent magnets …

A new design of VHGMS system based on NbTi composites superconducting magnet is proposed. The average magnetic field in separation area can increase to 2 T, which is beneficial to improve the ...

For instance, it is very difficult to separate trace mica and feldspar from quartz ores by conventional processing techniques due to their similar surface properties …

Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heat-resistant and does not conduct electricity.
