gold ore grade suitable for copper concentrate

the majority of large scale copper/gold ores is 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
