A separation apparatus and method for separating ore is provided. The separation apparatus (10) includes a separation chamber (12) and is configured to be utilised with a fluid pulsing mechanism (32) for operatively pulsating a fluid through ore deposited in the chamber resulting in the migration of generally lighter ore particles toward an upper region (25) of the chamber and for generally heavier particles to migrate toward a bottom region (14) of the chamber (12). The ore is deposited by means of a chute (38) in the bottom region (14) of the chamber (12) and the lighter ore particles may then be extracted from the chamber through a first chamber outlet (24) while the heavier particles may be extracted through a second chamber outlet (28).

Disclosed is an underground coal preparation process adopting a water medium, comprising: feeding exploited raw coal into a Φ25 mm raw coal classifying screen for screening; performing dry coal preparation on a classifying screen oversize product with a particle size greater than 25 mm and feeding a classifying screen undersize product with a particle size less than 25 mm into a special underground compact jigging machine for sorting to obtain jigging machine overflow clean coal, jigging middling coal and jigging gangue; screening and dewatering the jigging machine overflow clean coal to obtain a clean coal product, and screening and dewatering the jigging middling coal to obtain a middling coal product, sorting slime water to be sorted and generated during sorting to obtain coarse clean coal slime and coarse middling coal slime, and performing circulating water treatment on a final liquid.

Devices, systems, and methods for separating waste stream with high glass concentrations to recover desired materials are described. The devices, systems, and methods may include a wet separator, a multi-stage screen(s), shredder(s), rising velocity separator(s)/jig(s), magnetic pulley(s), eddy current separator(s), and/or optical sorters.

A method and machine for the purpose of separating heavy materials from lighter materials by specific gravity. The machine consists of a vertical cylindrical body, supported on legs, and across the top a flexible diaphragm of appropriate material is draped, and fastened at the perimeter. The diaphragm forms a bowl-shaped depression, and is manipulated by a rotating assembly. The assembly having any number of arms, mounted in a fashion in which they are offset from the center of rotation, and extending radially nearly to the perimeter. The assembly is mounted on a vertical shaft which may be turned by a motor, or manually. The force of the arms, acting against the underside of the diaphragm, causes an upward projecting, moving wave in the diaphragm. Raw material is fed through a feed funnel to the center of the diaphragm, forming a conical pile. The pile is agitated by the moving wave, causing the heavier materials to sink down to the upper surface of the diaphragm while the lighter waste moves down and across the pile, and over the edge. The machine operates either with, or without water. The heavy materials, once in contact with the surface of the diaphragm, move down the slope of the diaphragm to the center. The heavy materials are encouraged to move more quickly and positively to the center by the offset nature of the arms, which cause a sweeping action to the materials in contact with the diaphragm. The sweeping action also assists in holding the heavy material at the center, and preventing its return to the waste stream.
