The Knelson Concentrator is a compact centrifugal separator with an active fluidized bed to concentrate high SG minerals (Knelson, 1992, Knelson and Jones, 1994). It was initially developed for gold processing, which commonly employed semi-batch units, as the yield to the concentrate was typically below 1%.
In the enrichment tests, KC-MD3 model laboratory scale batch type Knelson concentrator was used (power 20 W, bowl speed 800–2425 rpm, capacity 0–45 kg/h, pulp solid rate 0–75%, maximum grain size 1.7 mm). Figure 2 shows Knelson concentrator enrichment experiment flow chart. In order to have a homogeneous distribution, …

the cost. In the late 1990s, the Knelson Continuous Variable Discharge, or CVD Concentrator was commercialised. This concentrator is designed to produce a continuous stream of concentrate and targets higher mass yield applications such as gold sulphide and heavy mineral recovery where higher mass to concentrate is required.
Knelson preconcentrate preparation studies were made with Knelson MD3 gravity concentrator having 4 different particle sizes, at 3 different G forces of gravity force of 90 G, 120 G and 150 G, under
The patented water injection process combined with centrifugal force allowed Knelson Concentrators to recover gold that was previously considered too fine for gravity devices. The concentration …
