Abstract:
     In this invention coke is used as the adsorbent for absorbing gold in the gold-containing waste residue and waste fluid, forming a gold-bearing coke. By means of floatation process, the gold-bearing coke is floated into the foam product of flolation and mixed with flotation concentrate, and then it can be smelted. So that the low content of gold in waste residue and fluid may be recovered. And recovered by the method can also be the gold in the sludge produced by floatation for separating complex ore in which the cyanide is used as the depressant. The method is simple in technique and convenient in operation, needs no additional equipment and investment, so the cost is low.
