This shows a portion of gold in table tails escapes both the mill circuit and the flotation circuit. So reducing gold in table tails by increasing recovery from the Knelson concentrate will certainly increase gravity gold. Furthermore the presence of free gold in final tails clearly shows the potential to increase overall gold recovery.

If a carbon-in-pulp (CIP) circuit were to be utilized for the processing of ore containing preg robbing components, then part of the gold dissolved in the leaching stage will be adsorbed by the carbon or clays present in the ore and result in gold losses to tailings. Recently, there has been a deviation from this approach.

We've got our cyclone for size separation, and then we've got our gravity circuit. The placement of the gravity circuit can either be on cyclone feed or here on cyclone underflow – I'd say this has been the traditional location in the underflow. And I'd say this is more of the modern location for the gravity circuit.
