A Knelson concentrator gravity recovery circuit treats the entire ball mill discharge for coarse, free gold recovery. The Knelson concentrate is processed in an intensive leach reactor (ILR). ILR leach solution is treated by direct electrowinning. The cyclone overflow stream flows by gravity to a linear trash screen ahead of a pre-leach thickener.
