low, typically around 1-2 g/t3,4. Flotation is the principal method of pre-concentration 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 by-product is also economically important7. The mineralogy of gold particles is usually quite different from the copper rich particles8, affecting ...read more
