copper gold flotation

Size dependent gold deportment in the products of copper

The concentration of gold in the majority of largescale copper/gold ores is low, typically around 12 g/t3,4. Flotation is the principal method of preconcentration for copper and gold5,6. Thus, porphyry copper ore concentrators are designed with the goal of maximizing copper recovery and grade however, gold recovery as a byproduct is also
