Study on Technological Solutions to Increase the Recovery and Quality of the Copper Concentrate at Ta Phoi Beneficiation Plant in Vietnam

The Ta Phoi beneficiation plant is one of the main copper beneficiation plants in Vietnam. The plant has been put in operation since 2019 and annually process more than one million tons of ROM copper ore to collect 32 thousand tons of copper concentrate of 23% Cu. In the first years of operation the plant’s metallurgical performance has not been consistent and not been as good as in design. The most important task at the company in this day is to improve and stabilize this performance with a target to obtain the copper concentrate of 23% Cu and recovery of over 91.5%. This report presents some research results to increase the recovery and quality of the copper concentrate at Ta Phoi beneficiation plant. As the results, some technological solutions have been proposed concerning the optimization of the reagent regime as well as of flotation flowsheet. Some of these solutions have been tested directly in the plant production line and have the perspective to apply.
