The key operating parameters in a Kelsey jig have been identified based on the understanding of its operating principle. Empirical models have been developed to predict the performance of the Kelsey jig while treating typical Indian coal fines at a given operating condition. Empirical models developed have also been validated with some …

The Kelsey Centrifugal Jig is an enhanced gravity concentrator capable of separating fine minerals and/or minerals with relatively small differences in specific gravity.

Kelsey Centrifugal Jig was found to be promising for the beneficiation of fine iron particles. The present study was carried out to have a better understanding of the separation process of Kelsey Jig through detailed experimentation. Beneficiation of fine iron ore fines was studied in Kelsey Jig. A constant pulp density (25% solids) of the feed slurry was …

The Kelsey Centrifugal Jig extends the effi cient size recovery range of fi ne mineral separation processes to 10 microns by combining the principles of conventional jig technology with centrifugal force. Spinning the jig increases the gravitational fi eld, which subsequently increases the apparent specifi c gravity difference between minerals.
