##tihuan2##Flotation of Cyanide Residues. Flotation is used to recover residual gold-bearing sulphides and tellurides. The Lake Shore mill retreatment plant is an interesting example of this technique. The problem here was, of course, to overcome by chemical' treatment the depressing action of the alkaline cyanide circuit on the sulphides.
