"Do you know where the first Knelson CD30 inches has been installed? East Malartic Mill, Quebec, Canada (CD serial 01 and 02) in 1993. The first commercial application for the low dilution cone has been done at this location in the CD serial 01. The results have been so good that the modified G4 cone to G5 has never been removed, except for clean up! The result of the 3 months tests run in parallel with the CD sn/02 gave a gold recovery better or at least similar to the G4 configuration, using only 45% less water in a 55% equivalent weight. The running time for the two Knelsons has been close to 99% on a 10 years continuous operation basis, recovered close to ~600,000 gold ounces and produced an extra gross revenue of ~$10 millions."

The advent of continuous gravity technology affords the opportunity to capture not only the free liberated gold, but also the gold carrying species into a small, high-grade concentrate. This concentrate can then be treated under more intensive conditions in a small, dedicated plant for maximum recovery.
