Performance of a pulsator-type coal-washing jig. Technical Report Yancey, H F Greer, M R Shinkosey, R E. The separation of coal from its associated impurities by means of a pulsator-type jig has been studied to determine the efficiency and the mechanism of separating coal and impurities in various coal-cleaning devices.
Traditionally in coal processing jigs have been used to clean the coarse coal fraction the 38 or material. Today with the advent of modern fine coal jigs in the United States its place was moved from the coarse to the intermediate coal circuit the 38 x 100 mesh.
An improved air jig apparatus and method is disclosed in which a dry magnetic separator is used to separate paramagnetic and ferromagnetic minerals from the dust component of coal cleaned with the air jig. The cleaned product of the dry magnetic separator is combined with the cleaned product of the air jig thereby improving both the quality and the quantity of the unmodified air jig product.
All together, the ineffectiveness of the air cleaning devices in treating fine coal has limited the application of this technology. Air jigs have specific advantages associated with the use of pulsating air rather than water. They have specific disadvantages also in that separation of coal particles larger than 45-50 mm is virtually impossible.

A new generation of centrifugal enhanced gravity separators is now available for fine coal cleaning. Commercially available units include the Falcon Concentrator, Kelsey Jig, Knelson Concentrator and Mozley Multi-Gravity Separator. These devices, which were originally developed in the minerals processing industry, are capable of upgrading ...
dry separator was acceptable for coarse coal -50 6.3 mm, removal of 6.3 mm coal which represented 20 -25 of the raw feed coal, reduced the overall yield of the clean coal. Pilot scale data indicated that when treating 50 6.3 mm run-of-mine bituminous coal 70-90 of the grater than 2.0 relative density rock could be rejected.
1.Status of coarse slime separation. With the improvement of underground mining mechanization level, the content of coarse slime in the selected raw coal is gradually increasing. In traditional coal separation process, gravity and dense medium separation are mostly used to separate lump coal. The former mainly includes jig and movable sieve jig ...
