The gravity separator is used for separating any kinds of kernels and granular products with nearly the samen size according to the specific weight. The separation process is carried out by means of the fluid bed principle.
Recent research has shown that froth flotation is not effective at treating fine coals ({minus}28 mesh) containing a large portion of middling particles. Due to their relatively large density differences, middling particles can be separated more efficiently using gravity-based processes. The ability of gravity separators to treat fine particles has been limited by the lack of …

The purification of metallurgical grade silicon (MG-Si) by using a combination of solvent refining and super gravity separation was studied. MG-Si was first alloyed with aluminum and then solidified at different cooling rates in order to precipitate dendritic primary Si from the Al-Si alloy. Primary Si dendrites were separated under super gravity, resulting in the ejection of Al …
