A 7.6 cm Laboratory Knelson Concentrator was used to evaluate the performance of one jig circuit (Snip Operation), four Knelson Concentrators circuits (Meston, Est Malartic, Aurbel and Hemlo) and one classification circuit (Agnico-Eagle). To determine the size-by-size unit performance of all units, total and gravity recoverable gold contents were measured in the feed, concentrate, tails, underflow and overflow. Sample dilution with silica was used as a tool to enhance LKC recovery in samples with a high sulphide content.
The data generated from the Knelson and the jig was used in a model designed to simulate an actual grinding and gravity circuit, and to predict its GRG recovery. It describes gold liberation, breakage and classification behaviour, and the GRG recovery performance curve of the chosen gravity unit. The simulation of the Snip circuit reproduced the recoveries obtained at the plant, and predicted that the use of a 20" Knelson, replacing the jig, would bring the recovery from 3 3% up to 43%.
