Effect of feed particle size and feed NGM on the cleaning performance of a Jig

ABSTRACT

Jigging is a commonly practised method to separate particles of different relative densities. Effect of feed particle size and feed size consist appears to be significant on the cleaning performance of a Jig. Most of the constituent size fractions of the Jig feed show different separation characteristics in terms of commonly used performance parameters. Though some literature suggest significant role of Near Gravity Material (NGM) in misplacement, in case of the Batac Jig studied under this investigation, NGM contributes very little to the misplacement of material.
