Counter Current Decantation at Central Norseman Gold Corporation Limited
As the gold price, and consequently ore reserves, improved in the late 1970's, a programme of upgrading the gold recovery circuit at the Phoenix treatment plant at Central Norseman was initiated. The introduction of oxidised ore with a high clay content from the North Royal open cut caused a reduction in thickening and filtering capacities, which in turn restricted plant throughput and increased gold losses in the residue solutions. Test work into alternative washing facilities showed that the installation of a five stage counter current decantation system would restore throughput and reduce soluble gold losses. Installation of the system achieved the objectives of increased plant tonnage, increased proportions of the high grade oxidised ore in the mill feed and decreased gold losses in the residue waters.
