The gold can be recovered from solution by direct electrowinning, carbon adsorption or zinc precipitation as required. This yields a much higher mineral recovery than the conventional shaking table for polishing of gravity concentrates. Leaching kinetics are accelerated by adding oxygen and agitating the solids with a high solidity impeller.

Intensive cyanidation onsite application of the InLine

Intensive cyanidation is proven technology that gives high recoveries from gravity gold concentratesthis was achieved by either a high speed agitator in a tank or by vat leaching. Both methods had their problems due either to excessive wear and high energy requirement for the agitated systems or channelling of solution and loss of fine gold in the vat type systems giving poor recoveries.

The traditional reason that intensive cyanide leaching on gravity gold concentrates is conducted is about managing security i.e. theft. While intensive leaching has its advantages, for example the gold enters the same soluble gold recovery stream as the CIL/CIP gold and more consistent 'quality' Dore is produced, smelting is a reasonable route
