  • Optimisation of gold recovery by selective gold flotation ...

     · The coarse gold fraction is easily removed by gravity concentration with the use of equipment such as Knelson and Falcon concentrators. These centrifugal concentrators are capable of achieving 96% recovery of free liberated gold coarser than 30~tm. The recovery of gold by gravity means is reduced considerably as the gold particle size diminishes.

    pregrobbing gold ores, yielding very low recoveries from traditional CIL methods. Gold recovery from the cyclone underflow was targeted to recover as much gold as possible in the absence of the fine pregrobbing carbon. Gold is recovered by intensive cyanidation and tabling of a gold concentrate produced by gravity from the cyclone underflow.
