"It must be noted that the Knelson Concentrator only treated a partial stream of the secondary cyclone underflow, being a test unit. Results would be far better if the total stream had to be passed through the Knelson Concentrator."
"The effective performance of the unit was under estimated originally. Any gold processing plant, treating ore containing free gold, fine or coarse, should select a Knelson to treat the total stream."
"The installation of the Knelson proved to be a profitable and valuable project in terms of improving the overall plant recovery and data gathering for the design of the gravity circuit on the new Target Metallurgical Processing Plant."
"Although difficult to ascertain the exact influence of the Knelson Concentrator on the overall recovery of Loraine Plant, due to changing plant feed grades and tonnages, it is fair to assume an overall plant recovery increase of no less than 3%." - Gerald E Olivier, Plant Manager- Avgold Target Division, Loraine Metallurgical Plant, South Africa
