FLSmidth said enhanced water distribution within the rings of the new GX Cone is the key breakthrough leading to "impressive recovery enhancements" in coarse and fine gold.
As water enters from the base of the new cone, it flows through zone separator nozzles for a customisable fluidisation profile.
This allows for even distribution of water in each ring and significantly increases the active recovery surface area.
"The result is a step change in overall coarse and fine gold recovery", said the company.
Mike Lefler, head of global product line manager for Precious Metal Recovery at FLSmidth, said: "The new Knelson GX Concentrating Cone is the culmination of over 40 years of research and operational experience and is exciting news for our customers … It delivers a win-win-win scenario: better recovery, less water use and less downtime due to easier maintenance."
