  • GOLD GRAVITY RECOVERY AT THE MILL OF LES MINES

    Recovery of -37 pm gold is lowest. This trend is disquieting for two reasons first fine gold is most likely to be classified to the cyclone overflow and second the Knelson s ability to recover fine gold is not fully exploited. Again test 3 with the double sluice at a higher feed density yields the best recovery for fine gold.
