By introducing the post leach filtration option which required an initial thickener to pre concentrate the filter feed a lower wash water ratio of 08 is used thus adding less water to the PLS Furthermore it is anticipated that the recovery of copper cobalt and acid through the filter is improved due to more efficient washing and the production of a filter cake containing less moisture The linear trash screen undersize reports by gravity to the pre leach high rate thickener where the slurry is flocculated and thickened to a density of 60 solids The thickener overflow is recycled to the process water pond for reuse and the thickener underflow reports to the leaching circuit
