10-Processing of the Gold Ore | Minerals | Gold

Re-processing Knelson concentrator tailing by sluice box improve both Au and Ag contents to 6.52 and 95.20 g/t respectively whilst their recoveries belong to 10.60 for gold and 9.36% for silver. The fact that 93.45% sluice box tailing retain only 0.026 g/t Au and 0.31 g/t Ag suggests that the tailing is not proper to be re-processed both technically and economically.
