The first and very crude Knelson Concentrator (KC) was commercialized in 1980 in Canada by Byron Knelson (Anastasakis, 2014, Knelson and Edwards, 1990, Being one of the enhanced gravity separators, the Knelson concentrator is basically a hindered settling device, related to a hydrosizer, using centrifugal force Determining the Separation Performance of the Knelson
The Knelson concentrator is a vertical axis bowl-type centrifugal concentrator that uses a fluidized bed to perform its concentrating duty. It was first introduced as a semibatch unit in 1982 and has gone through several iterations of design, leading to the development of a continuous discharge machine [ 1 ].Being an EGS technology, the Knelson concentrator op-erates based on teeter-bed principles in a centrifugal field to separate fine particles (Honaker et. al. 2005) Fig. 1 shows schematic illustration of a Knelson concentrator. This concentrator is a vertical axis bowl-type centrifugal concentrator and utilizes a fluidized bed to perform its con-Determining the Separation Performance of the Knelson

Knelson concentrator is previously used by several researchers for lowgrade samples with such fineness [14][15][16][17] [18] [19], and hence, Knelson concentrator may be opted as enhanced gravitytested using relevant industrial Knelson concentrator data. The analysis showed that a relatively coarse feed would impact negatively on the recovery between 106 and 425 µm. On the other hand, it would make it easier to recover particles between 25 and 106 µm. A finer feed would have a bigger impact on recovery around 25 to 106 µm andEFFECT OF OPERATING VARIABLES IN KNELSON
