Retreatment of Residues and Waste Rock

Today tailings from the all-sliming process constitute virtually all the residues from gold plants. The size range of this material is between 65 and 80070 minus 75 /-tm and typical gold values range from 0,1 to 0,5 g/t. In a few exceptional cases accumulated tailings have values between 0,5 and 1,0 g/t.
