Introduction: Jig concentrator (jig separator, jig machine) is a equipment that drives pulses of water upwards through a thick bed of settled sediment to keep it loose and agitated.This achieves gravitational separation by allowing the denser minerals to sink easily and quickly through the lighter minerals. A typical jig consists of a water-filled tank known as a jig-cell, …

The Fire Clay coal was subjected to a float/sink separation at 1.50 specific gravity with the 1.50 float being finely ground and subjected to froth flotation. The finely disseminated minerals appeared to be liberated to some extent as the feed to the test contained 118 ppm REE and the tailings contained 565 ppm REEs (whole-coal basis).

Hydrocyclones were invented in the late 1800s and became widely used in mineral processing because they are relatively inexpensive, process high volumes, take up minimal floor space and have no moving parts. Hydrocyclones are commonly used for desliming, dewatering and sizing -4mesh (5mm) particles. They can be used in industries such as …
