  • Flotation of Copper–Zinc Ores Handbook of Flotation

    Reagent schemes – modifiers and depressants. In the 1960s and 1970s, the reagent schemes used for treatment of copper–zinc ores were designed to maximize recovery of gold and silver. Although cyanide was extensively used, the dosages were minimal because of the adverse effect on silver recovery. The effect of NaCN additions on silver and gold flotation from East Malartic (Canada) ore
