?�Introduction: Adopting mixed flotation-concentrate regrinding process can reduce the grinding cost, and be easy to manage. Application of new non-toxic flotation reagents is efficient and environmental protection. ?�Application: Mixed flotation-concentrate regrinding process is applied for Cu-Pb-Zn sulfide ore. ?�Process Description Creative process, low operation cost Cu-Pb mixed concentrate regrinding process saves the grinding cost without fine grinding all the ores are, and it makes furth
